At the moment, there are a lot of crypto signal providers out there,
Compare this to the number of people selling fake gambling picks. See the similarity?
which is making it hard for me to choose the right one.
Why do you even want to pick them? If making money was so easy, would the people giving such picks, not use them to already become millionaires? Dont forget that everyone on the internet is out there with a motive and no one does anything for free.
A lot of these crypto trading signal providers have a good track record of giving out good signals, but some are only in it for the money. So, which is the best provider of crypto trading signals, and which one should you use?
You have answered your question yourself. All of them are in it for the money.
If you want to make money by trading you need to learn to read charts, identify support/resistance levels and the basic reading or indicators like RSI need to be known. Fundamentals are what is important for a newbie. Learn these and try to predict market movements yourself. It is not easy and neither is making money. But it is very easy to scam people by selling them fake picks - you get the idea?
