Solana's level of stability today is still quite good, I like the coin, but the problem is that altcoins are currently in correction, but if we can be patient and wait for normal market conditions, I'm sure Solana will provide maximum profits in the future, it will take time to waiting for that.
Usually if a coin is destined to go up and down based on market prices, it is not doing something great of its own and that is usually not good for investment. When the markets are up, and the coin goes up, that's nothing, I could have bought litecoin and made the same level of profit anyway, it should be going a lot more than what other coins are going up, or when the market is going down at the very bare minimum it should go down lesser than what other coins are going down.
All of these are very important aspects of the crypto selection process. You have to pick something that is independent to the market a bit, not a whole lot but at least a little bit.
