It's crypto/web-wallets, not traditional wallet.
Ethereum is a VM for example. Quite hard to see how it can be construed as a pyramid scheme tbh.
I’m very bearish on crypto generally, but DeFi has started to catch my attention a little bit, as it does have potential to shake up finance more broadly.
"When we hear people like Tether saying we're successfully banking the unbanked, you can look at the median transaction over the Tron network, and it's between $100 and $300. If you looked at comparable numbers in the US for credit card transactions, the median transactions is between $40 and $80. And so, do you buy that they're banking the unbanked third world who are moving a lot more money around than people in the US do?"
