The best time to buy a coin is after it has been dumped or before a pump
Why?
Because the people that didnt cash out during the pump (called “bag holders”) dont want to sell their coin at the bottom, at a much lower price. It goes without saying that if the price of a coin you’ve bought moves upward quickly, its best to cash out, back into Bitcoin. And If its a good coin that you want to invest in for the long term, make sure you buy back in after a dump. Sometimes it is better to focus on accumulating good coins rather than making more Bitcoin, because a good coin will always rise again.
That’s how trading is done.
