I think we have many problem with CryptoNote, should we change BitAsean to other algorithm?
Equihash would probably be better to be honest. Much more open and vibrant developer communities BUT, be honest with yourself. If you don't have enough experience launching a blockchain and maintaining it then it doesn't matter what algorithm you choose.
If your team only consists of 1 person (you), then it doesn't matter what algorithm you choose if you've taken on too much work for one person.
If you can't communicate daily with the people who have invested in your blockchain then it doesn't matter what algorithm the coin uses. People will lose interest.
That said, your best idea is a rollback of the current blockchain. So do it! People who have coins on this chain, who have bought or mined them deserve that. Don't abandon the chain you launched and try launching another with another algorithm because if you do you lose all credibility.
Take care of your CURRENT CryptoNote project. Rollback 1 week. Get the chain going again.
Even if you decide to switch algorithms you will need a working CURRENT CryptoNote blockchain in order to do a 1:1 coin swap.
