All the wallets went offline for the security reason because they told that 300k SCC coin were stolen and dumped on crex24. They also mentioned coins were stolen from wallet directly not by website. You can check their discord page for further updates.
These security breaches is beginning to become rampant, we hope the team and dev of Stakecube can increase security and have this sorted out once and for all
I hope so... It is a really good platform with some solid projects like shared dash masternode, bitbean staking pool, etc. I have some balances on there but because of risk factors I can not send all of my portfolio.
