Disbelief followed by skepticism should be your first reactions to this title. It does indeed look like clickbait. It’s not.

This article is a follow up to a previous article I wrote on DeFi. If you haven’t read it yet, read it first before reading this one.

Alchemix is a DeFi app that launched a few months ago and that claims on its website to provide “highly flexible instant loans that repay themselves over time.” With such a bold statement of course I was intrigued and decided to investigate. I wanted to understand how it worked.

While mainstream media has been focusing on Bitcoin, a parallel financial ecosystem is developing on Ethereum. Decentralized Finance, or DeFi, will disrupt how banks and financial institutions operate. The have never faced competition like this before.

Not a day goes by without another bank or financial institutions announcing new services related to Bitcoin. As the Bitcoin market capitalization rose to a trillion dollars, it has effectively become “too important to ignore”, as Deutsche Bank wrote. …

I have given presentations on Bitcoin many times over the years. Every time, I start with the same thing: a history of money.

The unexpected and sudden rally that started in April 2019 coincided with trade war tensions between the US and China and the New York Attorney General going after…


Every time Bitcoin crashes 80% or more, headlines all over the world claim that this time it is really the end of Bitcoin. These crashes have already happened several times in the past and will happen again. So does that mean that Bitcoin is a speculative investment?

What was happening was precisely the opposite. …
