It seems clear we’re not near consensus on this issue, so I’m fine with leaving things at status quo.
But I still strongly believe that the vast majority of cryptocurrencies, Bitcoin included, do vastly more harm than good. I was a Bitcoin early adopter in 2010, I definitely thought it had lots of potential for democratizing money. But now we have seen cryptocurrencies in the real world, and the vast majority of their uses are harmful, e.g. tax avoidance, money laundering, naked speculation, etc. On top of that, they are terrible currencies: expensive transactions, difficult to use, terrible security record, no way to reverse fradulent transfers, poor privacy, extremely volatile, and very energy intensive. If you are anti-fiat currency, then you should move away from current crypto-currencies because they make fiat currencies look so much better, with concrete numbers to compare. It was a wonderful idea, but it is clear now, it just didn’t work out.
Here’s one nice take on it, there are many others:
