Probably nothing. SmartBCH can recover if it delivers the decentralized bridge but that was promised one year ago and still not much to show. I hope it will recover, but I have also written off my smartBCH investment in tokens, NFTs, and platforms. At least most were able to transfer their BCH out using some options we had.
CashTokens is different, though, as it is on the Bitcoin Cash blockchain. There is no trusted third party involved (like coinflex), and transactions are even faster. I don't know the exact capabilities of CashTokens, but I believe we will find out within this and the next year.
