Is it reasonable or ignorant to consider selling my bag now that BTC has surpassed its previous ATH? I'm just a simple person without a finance background who follows the basic rule: "buy low, sell high"

Title.

I strictly follow the basic rule: “buy low, sell high.”

Back in early 2022, when the war in Ukraine broke out and markets crashed, I remembered that rule and started buying different coins while they were VERY cheap.

Now, in 2025, BTC has just surpassed its previous ATH, and Solana (a major altcoin) has done the same. Is it reasonable for me to consider selling now? Or would that be an ignorant move? I'm currently in profit, for context.

Sorry if my question sounds silly.

Cheers!
