Quick question, which is the most cost effective and reliable exchange to buy Tether using fiat, USD or EUR ?
Binance's fees for USDT/EUR are 2pct which is quite excessive, but it seems to be pretty competitive overall..
If you dont like Binance fees then dont use them. There are so many other exchanges available out there but you could try to instant swap options like shapeshift too if you dont mind going through a KYC.
But there are also exchanges like the ones you posted above and to be honest it is a personal choice.
Polls like these are not trustworthy since we can have a number of newbie accounts vote of one specific exchange to promote it and you will get a biased conclusion. So try them out one by one and see which one suits you the most. What is good for one person may not be good for you.
