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.
ROFLMAO.. and people are talking about USDT replacing fiat currency. To replace one asset with other, the latter should be having a lot of advantages and merits compared to the former. If we compare fiat currency with stablecoins, I don't think that this holds true. I would even say that stablecoins such as USDT are inferior to fiat currency. In case of USDT, I can't trust the exchange which creates this token (Bitfinex), as they have been accused of fraud using the reserve funds of USDT.
