I just sent them over and I can't buy anything with them... I thought I'd be able to convert them to usdt or buy btc with them... This is so dumb. Do I have to send them back and convert them and send them again...?
Don't need to repeat that again as there are so many pairs for DAI. So, just go to market section , than search "DAI" and you'll get the pairs of DAI where you can do trades to convert DAI into other crypto asset like bitcoin, ethereum, usdt or Maker (As these 4 pairs are available on kucoin). If you send back to metamask wallet, than you might need to spend high gas fees which won't be good choice for portfolio.
