Hi everyone this is my first post, seeking for a crypto signals advice

I am seeking about a realiable source for cryptocurrency signals and I heard that there is many good groups out there. per my check in Youtube and reddit, people are most talk about Whaleagent, blockchain whispers , and bitcoin barvado signals groups. however I am very confused. I have seen many great reviews about the Whaleagent but still consider my investment, however whispers channel is very expensive but I heard that it is one of the best too.
To be honest when I checked the channel history of whaleagent and the profits sheet, I was amazed. all of their calls are verified and made more than 300% for their subscribers in April 2018
