Cost to transfer USDT now: $20 at the very cheapest and slowest speed. Average is $40.
So the world's most popular stablecoin, and many other less stablecoins all using Ethereum will cost you that much.
How can it replace fiat currencies which are mainly free to transfer to each other (except cross border).
I support crypto but it's not yet ready.
Actually you got a point. But this is for centralized aspect. I hate the fee when using stablecoin usdt on cex since the fee is super high, but when you used decentralized wallet to process transaction you will pay via gas or eth gwei. Sometime its high sometime its low, but it didn't reduce your receiving stablecoin but only bear the appropate fee on the network unlike cex that deduct $20 is such a pain isn't it.
