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
Trading is not an easy thing. It's not like you said, buying when prices are low, and selling when prices are rising. There are times when we buy at a high price, but sell at a low price. For example, DeFi tokens (YFI) once hit the price of 4 BTC / YFI, and the current price is slightly higher than BTC. What if someone buys at a high price? Do they wait until the YFI price returns to 4 BTC / YFI? If so, how many years will we have to wait?
