Hmm... Thank you for that! You could explain to me the difference, in the C to the T; at the end of the “USD”.

I really don’t know and it may seem stupid I don’t know. But I really don’t know! 

 USDT is issued by Tether.  Tether use 15% of profits to buy Bitcoin, supporting Bitcoin.  USDC does not do this. I prefer to use USDT for this reason. 

 Interesting! I’ll get more information about this. Your time was valuable to me, know that, thank you!
