The apparent success of stable-coins, to me, represents the inertia of status quo, where the USD (or its derivatives) are still more liquid and better recognised assets than Bitcoin.

After all, Iran (unsurprisingly) is not really at the forefront of Bitcoin adoption, and even if someone has like 100 BTC in Iran, he probably has no way to spend it there. So probably they recognise USD more than Bitcoins.

I am not an OG< but all it shows, is that we are still early, very very early.
