Coinbase Referral

Coinbase Referral Sign Up

Hi – I’ve been using Coinbase which makes it really easy and safe to buy, sell, and store digital currency (like Bitcoin). Sign up now and get SGD 13.36 of free Bitcoin when you buy or sell at least SGD 133.63 of digital currency. Claim your invite now: https://www.coinbase.com/join/wu_t22

Coinbase is a listed company on Nasdaq, with ticker symbol COIN. As of March 2021, Coinbase was the largest cryptocurrency exchange in the United States by trading volume.

There are actually free gifts of crypto on Coinbase, just by signing up and watching some videos. The gifts are usually small amounts of lower cap crypto.

Coinbase Commission Fees

  • Coinbase charges a spread of about one-half of one percent (0.50%) for cryptocurrency purchases and cryptocurrency sales.
  • Coinbase also charges a Coinbase Fee (in addition to the spread), which is around $0.99 to $2.99.

Coinbase Singapore Review

Coinbase is quite fast for signing up. You can signup online within minutes. Note that they may require some identity verification such as ID (NRIC or passport) and a document containing your address (utilities bill, or bank statement).

The mobile app of Coinbase also has an excellent design, and is extremely user friendly.

Coinbase Minimum Deposit

There is a very low minimum deposit for Coinbase (around $50 recommended), and there is also virtually no minimum number of crypto you can buy (can buy as low as $2).

Is Coinbase Safe?

This is the most frequently searched question. Firstly, Coinbase has been granted a license exemption by MAS (Monetary Authority of Singapore). Their MAS exemption can be found here.

Secondly, all digital currency that Coinbase holds in its online hot storage is insured. If Coinbase were to suffer a breach of its online hot storage, the insurance policy would pay out to cover any customer funds lost as a result. 

Thirdly, Coinbase is regulated by SEC (U.S. Security and Exchange Commission). Their SEC license can be found here.

Lastly, for added security, there is 2-Factor Authentication option for Coinbase. Sometimes, there is 3-Factor Authentication (email authentication as well). You can set it up during registration, by providing your phone number and email.

With any investing, there is always some risk, so do your research carefully before investing using any broker!

Last few months to mine Free Pi Coins (Referral Code: math88pi)

Pi Network Invitation Code: math88pi

I am sending you 1π! Pi is a new digital currency developed by Stanford PhDs, with over 10 million members worldwide. To claim your Pi, follow this link https://minepi.com/math88pi and use my username (math88pi) as your invitation code.

It is literally the last few months to mine Pi Coins, Mainnet is launching in estimated Q4 2021 which is just a few months away.

Pi Network has a halving procedure in place, similar to Bitcoin. Basically it means that, the mining rate will reduce by half  when a certain milestone is being hit (usually in terms of number of members). Eventually, the mining rate may even hit zero. This means Pi Coin eventually has a finite supply, just like Bitcoin.

We have a detailed review of Pi Network and Pi Coins in a previous blogpost.

Pi Wallet will be released on 31 March 2021

On the Pi Network’s official Twitter page, they announced that they will be releasing the Pi wallet on the Testnet with Test-Pi on March 31, 2021.

This is quite an achievement, Testnet is usually just one step behind Mainnet. For example, Ethereum has several Testnets such as Rinkeby Testnet. The Testnet can act as a test or experiment to see if there are any bugs, before rolling out the Mainnet which contains the actual Pi coins.

Pi network vs Bee network

In the previous blogpost, we detailed some reasons why Pi network is likely to be legit.

Unfortunately, the same cannot be said for Bee network:

  • Bee network is created by anonymous/unknown people.
  • Bee network is just a “clone” of Pi Network in many ways, up to their White Paper.
  • Not sure if Bee network is a legitimate blockchain project, or just one that is trying to ride on the waves of Pi Network.

Hence, currently, we recommend Pi Network but not Bee Network.

Pi Network Review

Pi Network is an upcoming blockchain, with idea similar to Bitcoin, but yet with certain differences:

  • Pi Network uses the Stellar Consensus Protocol, while Bitcoin uses Proof of Work.
  • Pi Network is currently still in the early phases, meaning that it is not available on the “Main Net” yet, or on any exchange. Bitcoin is already very established as of 2021, even recognized by major institutions and banks.

Is Pi Network Safe / Is Pi Network Legit

While it is impossible to answer with 100% certainty, one can list at least 3 reasons why Pi Network is legit:

  1. Pi Network is listed on the Apple App Store. It is known that “Apple evaluates every app in detail before it’s available in the App Store to make sure that it doesn’t contains viruses.”
  2. Pi Network is created by real known people (Stanford PhDs: Dr. Nicolas Kokkalis and Dr. Chengdiao Fan) who put their real name upfront. Their identities are verified by Stanford Daily, which is the official student-run, independent daily newspaper serving Stanford University.
  3. No money is involved in using Pi Network app. No credit card details are needed. Hence, it is impossible that Pi Network is trying to scam money since no money is involved.

Is Pi Network Worth Anything

This is another popular question, on whether Pi Network is worth it. Firstly, Pi Network only takes few seconds per day, to tap the mine button. Hence, the total time wasted is very minimal.

Secondly, once Pi Network goes live on the Main Net, it has to be worth something non-zero. Many YouTubers have analyzed its worth (Pi Network price predictions), the below video has quite a mathematical estimate of what Pi Coin is worth.

Pi Network Mining

Pi Network coins are able to be mined on a mobile phone. They are very unlike the Proof of Work algorithms which require massive amounts of electricity and computing power. In fact, the coins can be mined without WiFi or running in the background.

What is happening at this stage is actually “pre-mining”, which is consistent with the Stellar Consensus Protocol (SCP):

Pi Network differs from traditional cryptocurrencies in that the coins are “pre-mined” or pre-generated from the start. When you initiate mining on the Pi Network app, you are simply being a distributed a set amount of coins per hour. Because the coins are pre-generated, your phone doesn’t do any heavy computational tasks, and power impact is minimal.

The mining of Pi Coin has a halving stage, just like Bitcoin. Eventually, the mining rate could even fall to zero. This helps to reduce inflation.

Ethereum in real life (Duke University is teaching Ethereum)

Ethereum has started to see many actual use cases in real life. For instance, major companies like Amazon, Microsoft, Google, Visa are all starting to adopt Ethereum as part of their real life usage.

Ethereum has started to appear in education as well. Duke University (one of the top universites in the USA), has started teaching modules of “Ethereum and Smart Contracts” as part of the syllabus.

Course description (Ethereum and Smart Contracts course in Duke University):

“Learn how to develop smart contracts and decentralized applications on the Ethereum Blockchain as well as history and trends of Ethereum itself. Ethereum is the most promising decentralized smart contract platform, and blockchain developers are in high demand. Learning these skills will give you a leg up in the blockchain world, especially in the Ethereum ecosystem. We will cover Ethereum (the platform), Solidity (the programming language), Truffle (the developer framework), and web3.js (the front-end library). Preference: some blockchain/cryptocurrency understanding. Prerequisite: basic programming skills.”

Trinity College of Arts and Sciences at Duke University


Ethereum Book

Learning blockchain technology should be a very marketable skill in the near future. Currently, there are two main ways to learn it, through online courses or through books.


Mastering Ethereum: Building Smart Contracts and DApps

The book above is authored by Dr Gavin Wood, who was the creator of the Solidity language and cofounder of Ethereum.

Ethereum Real Life Applications

Recently, the blockchain Ethereum is starting to gain widespread acceptance, many major companies such as Microsoft, Google, Amazon are already using it.

In terms of publicity, Ethereum is still behind its more famous cousin “Bitcoin”, but that should change in the near future. In fact, many people have postulated that a “flippening” may happen where Ethereum takes over Bitcoin as the cryptocurrency with the largest market cap.

In this blogpost, we list the real life applications and uses of Ethereum, using official sources as far as possible. That is, if Google is using Ethereum, we will try to point to the official Google website instead of a third party news site. Otherwise, we will only use very reliable third party sources such as Forbes, etc.

Amazon Ethereum Blockchain

This is very recent news, on Dec 21 2020. Amazon Managed Blockchain now supports Ethereum. With Amazon Managed Blockchain, AWS (Amazon Web Service) customers get secure networking, fast and reliable syncs to the Ethereum blockchain, durable elastic storage for ledger data, encryption at rest and transport, and secure access to the network via standard open-source Ethereum APIs.

Official Amazon Ethereum Blockchain news: https://aws.amazon.com/about-aws/whats-new/2020/12/amazon-managed-blockchain-supports-ethereum/

Google Cloud & Ethereum

Ethereum can inter-operate with Google Cloud’s enterprise cloud data warehouse (BigQuery) via oracle middleware (Chainlink). At a high level, Ethereum Dapps (i.e. smart contract applications) request data from Chainlink, which in turn retrieves data from a web service built with Google App Engine and BigQuery.

Ethereum Blockchain as a Service on Microsoft Azure

Microsoft and ConsenSys (a blockchain software technology company) are partnering to offer Ethereum Blockchain as a Service (EBaaS) on Microsoft Azure so Enterprise clients and developers can have a single click cloud based blockchain developer environment. The initial offering contains two tools that allow for rapid development of SmartContract based applications: Ether.Camp – An integrated developer environment, and BlockApps – a private, semi-private Ethereum blockchain environment, that can deploy into the public Ethereum environment.

Visa Ethereum

Visa announced it is connecting its global payments network of 60 million merchants to the U.S. Dollar Coin (USDC) developed by Circle Internet Financial on the Ethereum blockchain.

Forbes news: https://www.forbes.com/sites/michaeldelcastillo/2020/12/02/visa-partners-with-ethereum-digital-dollar-startup-that-raised-271-million/?sh=5dc04f484b1f

Visa didn’t quite announce it on its official Visa website, but we can see that Visa is actively recruiting engineers with Ethereum and Solidity (the programming language on Ethereum) experience.

Visa is actively recruiting engineers with Ethereum experience:

We’re seeking a strong developer experienced with Ethereum and blockchain architecture to be a part of
team tasked with building distributed application. Our ideal candidate has built and released distributed
applications, has worked with the Ripple, R3, Ethereum and/or Bitcoin blockchain, and has experience with Solidity

Multiple Positions are available in Austin, TX and Foster City, CA locations

Ethereum JP Morgan

The Blockchain Center of Excellence at J.P. Morgan leads efforts for Distributed Ledger Technology applications, actively researching blockchain use cases to develop in-house technology and pilot solutions across lines of business within J.P. Morgan.

The program also manages strategic relationships and investments with key vendors and consortia, including Enterprise Ethereum Alliance (EEA). The Enterprise Ethereum Alliance is a member-led industry organization whose objective is to drive the use of Ethereum blockchain technology as an open-standard to empower all enterprises.

Official JP Morgan Ethereum news:

Other Ethereum use cases

A full list of companies using (or interested in using) Ethereum can actually be seen on the Enterprise Ethereum Alliance website, under the members section. We can see that many big name companies are part of the Enterprise Ethereum Alliance, including:

  • Accenture
  • Baidu
  • Dell (Boomi)
  • Ernst & Young
  • Intel
  • PricewaterhouseCoopers LLP
  • Standard Chartered Bank
  • VMware, Inc.

It is interesting to note that 2 of the “Big Four” accounting firms, Ernst & Young and PricewaterhouseCoopers are interested in Ethereum and smart contracts, which could potentially change the accounting industry.

According to Business Times Singapore, 80% of current accounting tasks will soon be done by machines, displacing humans in most junior finance roles.
