How do you decide when to sell cryptocurrencies? Enjoyed some gains on some coins now but not sure how much of my portfolio I should sell or whether I should sell them. Any advice? Thank you.

Take out enough to get back your capital and look for “undervalued” coins. Which typically mean Low market cap with high catalyst potential like a main net launch or some new use case.

You can use the total current market cap of the coin as a general rule of thumb.

For speculative coins, I usually sell all/half of my holdings once I reach a 50%/100% profit, which is what I did for AVAX recently. I bought AVAX at an average price of $17, and I recently sold my initial invested amount at $47, and I am just letting my profits run now.
