Thinking about cashing out

I feel like i’m waiting for my portfolio to go to its peak again.. Solana is what made it peak when the price was at like 280 .. I feel like I’m gonna get too greedy and it’ll just crash! I’m debating whether to swap to stable coins rn and wait to jump back in hopefully if stuff goes south in the future.. Idk man I just fear missing a big run and missing out on so much more. I’m only 19 rn but got $22k currently it peaked at like 26k

But imagine everything goes crazy and i miss out on 40k+

I’m really not made for this aha
