I do not advise to participate in such schemes. I have been working with cryptocurrencies for more than 5 years. I researched many channels in Telegram that offered both paid and free signals. They're all crooks.Forecasts come true for 40-60%.
It's always good to have our own research and analysis so that we can be sure about what we are doing and taking care of our capital is possible and everything will be under our control. Buying signals will lead to disasters because no one will take lots of hours for generating accurate all. They will do like a routine job and that is the reason they are producing only 40-60% target hitting.
People are going for buying signal just due to the reason of they are new to crypto trading. But, no one should expect to make profits from trading from their beginning days itself. They must learn first so that they will be capable of generating their own calls only after that they should enter into actual trading.
Learning and then entering into actual trading with small capital for the purpose of practicing are the steps, everyone should follow. Instead of trying in actual trading, most people go for paper trading which is a working way of preventing unnecessary losses. But, if you want to experience the real heat of markets then you must go for actual trading but with very small capital.
