We all want to be rich in crypto space, I get it but there is possibility that what we want to achieve may not come to past when we plan only to hold coins and tokens for years but how about
Buy a coin and hold like you intended but take profits when the coin shoot up like double Profit up to 2x and buy back when the coin dumps, crypto is like a circle, there will be pumps and there will be dumps, in that process of taking profits and buying back you will end up wining both ways, whatever happens you won't entirely lose out.
Think about it
I agree that we shouldn't be too attached to one or more altcoins. Altcoin price movements are quite sharp and change quickly, if we don't sell when our target is met, then the momentum can disappear in an instant and it's better to relate the profits that are in sight
