Yes, Hitbtc exchange should be removed from the coinmarketcap ad coingecko because they are charging very high amount and many people have lots of complaints about the HitBtc exchange, that's why we should be very careful with the exchanges.
This exchange site was charging a very big fees to its users. The users will not able to withdraw any amount that multiple from 100 or more
If someone had 1555 coin and he can only withdraw 1500 and the remaining of coin will stuck on the hitbtc.
People just need to block it and it will be the best solution that can be taken by anyone.
