Well thank you for a useless platitude, but if you have then you should know that you invest based on potential you see. Its putting your money behind something you believe in.

Understanding the potential of the investment gives you room for accepting changes in price. If it could plausibly reach 50usd then movements of 50c are nothing, if it can reach 5 usd, then you might sell at 4 to avoid a crash.

If someone said to you they're holding a new share from an IPO for 5 years because in that time the company will be 100x bigger than shell, and then refused to sell when it peaked at a similar market cap to shell they'd look like an idiot.

Surely the same applies to crypto, understanding the potential for growth based on the market caps of the current largest coins, and expected trajectory of the coin you back comparatively.
