Oh no, I wouldn't dare to deposit $50 to that. I will not take the risk with my own money and will cry at the end. To be honest, trading bots aren't profitable as they are promoting it. The OP stated % profits which I highly doubt.
However, if you want to know some trusted trading bots. Try to read this
article as it stated some feedbacks, backgrounds of each best trading bot that have mentioned in the article.
I have nothing against the OP, it is good to see people developing a software especially when it contains something useful for the crypto and traders actually $20 is quite lower compare to others that has a monthly billing. What I am doubtful about is the $50 minimum initial take with bot and the claim that it is gaining 8% a month, most probably that is just a series of good trade for 8% every month so that does not count.
