Honestly I don't like both exchanges but between the two I prefer trading on Qtrade than QBTC,I have traded several times on QTRADE but never on QBTC I've been reading a lot of bad things about QBTC in the IDENA price telegram, I hope after we move on the mainnet we can get in a much better exchange.
What is it about qtrade that you don't like?
Just a feeling maybe because in the past I have been scammed several times by new exchanges in the market, some of them even launched an ICO but so far they are doing good in catering for the IDENA community but a big exchange like Kucoin and Binance will kick the price, it can easily get into Kucoin by voting but it will take sometimes for this to happen as we are still in testnet.
