If a coin that we hold and have earned a profit is certainly something we always want and to buy again when the decline occurs on the same coin of course we must really consider, because greed often makes us panic because it does not go as we expected, as is the case today very many investors are stuck in certain projects because sharp declines continue to occur.
Not really, we cannot redeem a coin while we consider it a risky investment and a surfer investment, it depends on the coin you hold, I will never buy back a shitcoin I sold before at the top.
When investing we should classify potential coins and speculative coins, with potential coins you can sell when the price is high and buy back when the price corrects, with junk coins, once they sell for a high price, it's best not to go back to look. They will become a dump soon after, once profitable then remove them from your head.
Well, shitcoins should be avoided since they didn't have real progress in their development and only pump and dump happened there. If we're looking for a quick profit with really high risk then shitcoins may be an option and we should prepare that we can lose our money in there very quickly too. Holding shitcoin is the same like you digging your own grave tho better to look for another good project with real development.
