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.
We all know today that trading is tough work even you are trading for a short term or long term it takes a lot of things to consider like always need to be updated in the market price, which coin will good for the trading technique we use and also check if we are earning. Today many people getting tired by this process and find some easy way to make a trade and earn money without doing anything, and this is the trading bot. This machine automatically generates a trade if the price is pumping and holding the coin if it is dumping. This kind of device is beneficial because you can be productive at other things at the same time you are earning. Using a trading bot is risky too because if then programmer manipulates the algorithm of the bot, it can cause a lot of losses and damage to your income. Still, I will prefer to continue learning in trading instead of losing and risking my money.
