I do not understand why folks keep saying if you use Coinbase with 5d, you will get banned. I am starting to question if folks really understand how BTC transfers work. If 5d was giving out the same BTC address every time you had a tramsaction with them, I'd def agree you will get banned sooner than later.
However, 5d a while ago started to create random addresses for *every* BTC transaction. That means these randomly generated BTC addresses are one time use only (but realistically they are not). Therefore, the odds of getting banned is extremely slim unless you're dumb enought to say "for 5dimes" or "for wager deposit" on the comments.
The above said, I challenge anyone to post a pic that they've been banned sending BTC to 5d the past couple years. As long as 5d is randomizing BTC addresses, you should never be banned assuming you add the wrong comments with the transaction.
