So I tried to deposit Grin on Bittrex when there was an error on their side that went away after I refreshed and it provided me the response file after that error, I didn’t want to take any chances on loosing funds so I canceled the deposit in grin++ wallet.
Apparently you need to contact Bittrex Support to cancel a Grin deposit. What? Why? (see screenshot)
BTW, why doesn’t Grin uses regular addresses like Beam to make transactions?
