Bitcoin and Ethererum have been having problems dealing with the volume on their networks lately. These networks the exchanges have were designed to do like 40k transactions in a day and now all the sudden its at 200k+ so its taking longer as exchanges especially figure out how to process you. Coinbase is awful with this I had one transaction take 12 hours for bitcoin.

thank you for your explanation!

What!? 12 hours is the longest I've heard of

Look up 0 confirmations in 8 hours....its a reddit post 12 hours was a pretty common delay

Ok, thanks
