there are many crypto platforms with fast transactions, but I think it is TRON that is still good. it's a quick deal, a cheap unit. and easy to use. but it still has a fee. USDT using the tron platform has 0 fees. so that the transaction is complete before the coffee is made.
each platform has its own advantages and disadvantages. if something is free and has good performance then users will certainly increase rapidly. when that happens, the role of the developer continues to make updates is very important. Regular maintenance is also important if you don't want the user to leave because of a system error that made the user uncomfortable.
