You mean the market accepting new coins? Sometimes new coins get big pump with multiple times, making huge profits for investors.
Is there a way to predict future pumps though? Or is it just pure luck?
Predicting when the market is going to go up is something that is very difficult, technical analysis alone is not able to give you that information because technical analysis only takes into consideration the past and tries to look for patterns in the movements of the cryptocurrency that you are watching, a way to try to protect a pump is to look at the fundamentals and see if an important news is about to happen, if you are able to time your investment correctly you could catch the pump.
