Bitcoin price has been pumped very fast for a few days so the price correction of Bitcoin is affecting all other coins but it will not last long. This is a temporary problem when Bitcoin price correction period is over when Bitcoin starts pumping again or if Bitcoin price is stable then bull market of Altcoin will start so if one wants to buy Altcoin now for long term holding it will be able to give good returns. so if someone have enough money for long-term investment then they can do it
Crypto is a super volatile asset class -- one level above gambling sh*t. There lies an opportunity for someone who is patient enough and has emotional and mental fortitude.
I don't believe the way crypto markets operate one should hold when the investment is well diversified. I think the retail investors should cash out their profit in every cycle.
The goal is to hit that 10x on the original investment, then take the profit and flush it to a more stable investment vehicles such as regular stock markets. And as you age, profits from those riskier investments such as stock should be siphoned to more conservative investments -- dividends/bonds etc.
