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
Mate this has been followed by many even now, what you meant is even if you loss you can make money from the dip by buying it again, correct me if I am wrong. This strategy is going from decade's and this is what it is done in share Markets as well. However this was a useful tip and this will definitely help us to avoid loss.
