But what will happen if the money stops flowing in the right amount?
If there's the sign that there's no money flowing in anymore for these stable coins, I think the first thing that we'll see is the decrease of the rate that they're giving.
Honestly, if I've got a lot of money and I want to stake, I'll simply put it into stable coins and stake it. I'd like it much than the other staking coins because it gives stable amount for its percentage and the coins itself.
