Now many things happening, So anything can be the cause of this things. FTX scammed the people funds, So they boosting the many coins like Solana. The FTX may do the transaction of their coin to buy the Binance coin. As I said, the price of Solana had started to increase to the very high value now. So its better to hold your coins in cold storage as compared to the exchange. Exchange can be closed and stole your money.
It is not recommended to store coins or some money in any exchange because the risk and level of security is very different from the wallet that we manage by ourselves. In the case of FTX, I think a lot of people have discussed it and many people know about it, but for the issue of upgrading to an altcoin like Solana, I don't think it's the only altcoin that's increasing now. You can see several other altcoins such as BNB, Tron, LTC, XRP and also several others, does that also have something to do with the case that happened with FTX?
