That is actually great news. I tried it already, but just with a small sum. As some of here below mentioned, for BTC, the price is so huge and it even doesn't make sense to convert small sums. USDT is not that good for small sums. So I tried TRX. It worked well, with a low fee, without KYC or any registration process. Perfect, really.

I am not sure if the fixed fee is a good solution because of the BTC sending, but I understand why it is.

I would love to see more currencies added of course, but as I understand, this is just a beginning and few more will come. I would suggest those with low fees so it makes economical sense for the traders. So ALGO, ADA, XRP, EOS and maybe Litecoin.
