What I usually do to confirm this trading signal is by comparing their chart to other's chart at tradingview.com.
If you get getting some points on a chart from some other source, its better to throw that chart away because those are pump and dump groups only. Better do your own work analyzing the charts.
I also analyzing the fundamental results or cryptocurrency news if it will be a bad or good news.
There are a lot of crypto related news happening everyday but not every one of those have am impact. The weightage of news is often exaggerated.
There are some patterns to be recognized what will be the next color of candle will appear and honestly, there are different kinds of trading patterns so it will be pretty confusing specially if the fundamental results doesn't match on the technical results. The safest thing to do is to not to set too much expectation of return of investment.
You could just play the hodl game and stock up at the low prices and then go to sleep setting the alarm clock at the price you want to sell. This wont work for those who are day-trading.
