808 Coin has undergone multiple hard forks costing Btcpop and coin holders lots of staking rewards. Btcpop has undergone extensive efforts to correct this, but the problem is with the coin itself and the developers have refused to fix the issue and been outright hostile against Btcpop.
If you have 808 please withdraw ASAP and refer to https://btcpop.co/808-guide.txt as the coin splits often.
