For those who are thinking of closing their investment in crypto, the best time to exit is when you need the money.
But, if you are investing on shitty coins, you will have to wait a lot for the coins to rise in value. If you are investing in common coins like Bitcoin, Etherium or Solana, just wait.
If you need a more conservative way to invest, wait until the benefits of the coins are larger than the money you made and move the surplus or more to stablecoins.
