In this time, those people can be considered as a rich who are transferring their funds through using Ethereum network. By the way, it doesn't matter how much the fee is for big gamblers.

From those sites, TRX, USDT is the most usable cryptos. This time, I also choose other altcoins like Trx, Doge.
