Edit: It's USD1 not TRUMP. So finally he's figured out how to make a coin that doesn't flop. Still, nobody in crypto is going to abandon USDT/USDC for this. Justin Sun will have more adoption on his USDD than Trump. Just saying.
Many stable coins have tried but USDT and USDC have been the most dominant. I think they will make up more than 80% of stable coins marketcap.
But I think USD1 tried as its marktcap is more than 2 billion dollars now. Those Trump family are very wise, they are doing nothing in crypto than to make money there.
