Got a free trial for 2-3 days from @Maxpizza and here's my review:
The guy was fast to deliver the product and really nice and talkative. He explained to me all the things I needed to know when joining those telegram groups. On the other hand he was too persuasive towards me asking me 1-3 times a day how I was trading and when I was going to give a vouch, BUT that might be considered as a good thing to too many people who maybe need an assistantance and him being active 24/7. In my case,considering the fact that I was pretty busy IRL (I shouldn't have asked for a vouch in the first place,so my bad) I felt observed by.
Talking about the telegram groups: Tried them a few times and read through their old stuff. Being someone who has been in the cryptotrading community for too long I didn't like a lot of what I saw BUT for a newbie who knows nothing at all,that's a good start to begin with, you can make some good potential money. I, on the other hand didn't feel the need of following those posts as they didn't feel like worth using,but again, it depends on what you're looking for. If you're expecting of making a lot daily or weekly, you're totally wrong. It will go slow and steady. Some days you will lose, and other days you will gain. An example it was the dip that just happened. When BTC was 31-32k, it was predicted it would go 34k and it went down to 29k,so yeah, that's how it is.
For the rest, I suggest you talk more to the guy who offers the service and ask even for a few hours trial as I think that the best way to understand the service is by seeing it with your own eyes.
