In the market as it is now, many altcoins are rising in price. Like a pumped solana and luckily those who have sold at peak price. So don't try to keep holding it, because it will definitely dump. I will sell altcoins when the price has gone up, but will not hold them for the long term, because to get back pumping, altcoins have to wait for bitcoin to return bullish.
If the altcoins you hold already reach its peak price or had a huge increase then its time to sell.
Always take advantage the every highs because we never know what lies ahead. Yes some alts who get dumped needs btc to recover back because btc influence the price of alts but this is not the case for some alts who dont have use case.
Dont be greedy and take profit at times, there's always a chance to buy back if the price experience a correction.
