The price will be dipping even deeper than before. The dead of solana is ahead of us. I just avoid to buy any tokens that strongly affiliate with FTX at this moment. It's very risky investment pretty much the same like doing future.
As far as I know FTX invests and will get about 58 million Sol tokens and it will be allocated until 2025 which means they also won't be able to get a chance to dump Sol in one go. FTX is Sol's biggest investor, not the blockchain operator solana. So whether Sol will continue to develop or stop is the decision of their team, not the decision of FTX. I don't like Sol because it's too centralized, but judging by it I still believe it can get through this tough period.
