Thank you martyf and Justin for your replies.
After a month of trial, I am still a little skeptical regarding the performance of the Crypto-ML algorithm. In my feeling, it is following the trend and reacted a little too late. Your explanation helped me to confirm my initial impression.
At this point I am not totally convinced of the benefits of ML since most signals were triggered too late. But I am willing to give it a shot and hope that it will perform better over the long run.
While I am still not 100% sure, you might have won another subscriber. I will have to make my decision tomorrow when the free trial time expires.
What I definitely liked was the fast and competent communication.
