Well i just started using bittrex since a week and don't get any problem..
But i m worrying after seeing so many posts here..
And also i have given my passport photo to them...so can i say i m safe ?
there is one issue regarding the way they ask for passports, naturally, any website that asks for your license or anything else to confirm who you are, SHOULD remove it from their data base AFTER confirmation, but, THEY DON'T !!!! go figure the rest
Also, if you read the post above you, there were many people who HAD verified accounts using their passport that now have disabled accounts
