You are right, there might be a pump, no one knows for sure. But if you have watched the buy and sell laddering tutorials (and all the others) and followed the methods by @haejin, you know how to:

• Estimate the best time to buy the coin to get it at the cheapest possible price
• Set-up your sell target i.e. estimate the length of wave 1 , 3 and 5.
• Set-up sell orders, to sell near the high before the corrections.
• Set-up stop loss orders, to minimize your losses if the coin dumps.

AND, then you will still make MASSIVE PROFITS in the pump, and get out before the dump.

Soo, your comments really show that you have no idea what @haejin and crypto trading is all about.
