Although they have highest measure of security and they keep all their funds in cold wallet to prevent hack but that caused delay.
I am sure once the improve this, there is not stopping decoin getting on top 20.
I got it, so that's the thing that caused delay, I feel sorry if an user only move a little bit of funds, then have to wait a long time, it's not really worth it. They really had to think of another way like not putting all the funds into coldwallet, but is it possible to make a split wallet for the "funds"?
