So, in my personal opinion, the surest way to success in crypto trading is to find a "pump finding application" and find out the approximate time ticker duration. Then buy at its lowest lower low, wait for it to reach its highest higher high and then, you sell your cryptos.
I've been using this technique for the past six months and I've had 73% success rate so far.
Buying the dip, you meant?
Anyway is a good strategy both for short and long trades. I think one of the most important things is to take note of the support and resistance levels. This will help determine the buy and sell points. I prefer this kind of strategy on a sideways market rather than on a trending market because sometimes when a trend starts or is about to start, Resistance and support can easily be broken
