I've been using this technique for the past six months and I've had 73% success rate so far.
And for the apps, I've been using "Crypto Pump Finder" for the more well-known cryptos. I have been using "Coinstats" for cryptos that are less known and remote.
So this is the reason for creating this topic.
I don't think pumping and dumping is a good strategy for beginners, especially on well-sized platforms that have some rigor in listing currencies like Binance.
waiting for the bottom is a good strategy, but it will only work with currencies that have a future and that are betting that they will rise, not all altcoins.
In fact, 90% of altcoins fail to reach ATH and may not reach it again.
Also, the rate of rise may be 100% within a year or two, which is less than what you can achieve with many strategies.
