I have used the Heat exchange for a while now. Its a solid, trustworthy exchange and I am thrilled that XEL is on it.
My one disclaimer for this exchange is: Read the instructions carefully when you are withdrawing, you need to do some additional tasks aside from an amount and a recipient address.
100% agree with you. I have being using it for awhile now too. The only issue they have now is manual BTC withdrawal. It took them 3 days to send BTC to my wallet last time. Other then that, I have never had any issues with HEAT DEX.
