There are a lot of such signal groups for crypto trading are available in almost all social media but if you are asking for accuracy them I'm sure you will find anyone. Because, almost all signal providing services are scammy ones they will just provide some signal but they are never responsible for accuracy. I have tried many such signal providers in the past but finally I concluded I am better than all of them in generating good accurate signals.

My kind suggestion for you, better go learning basic of technical analysis and then you will be able to generate accurate signals for your trading purposes which will give peace of mind and at the same time will save costs as well.
