This automatic bots that are being posted in public will never be profitable, and I will explain why.
Once the trading bot goes public and everybody uses it, it means that you have a lot of people who trades the same way as you in the exchange, so you can't actually beat them, you will be equals and you will end up losing money.
On the other hand, you are risking your funds here because the bot operator can just choose to use all it's users money to manipulate some coin's price.
Brother the thing is that the service receives half of the profit that it will earn the user, which means that the service is interested in trading the maximum profit, its income depends on it. The service does not use a public bot. APItrade uses its own algorithms, the most modern developments, the work of the algorithms is monitored by a team of several hundred professionals, plus several thousand users who monitor the work of algorithms every minute and adjust the settings, optimizing the work for maximum profit. This is not a public bot algorithms which are known and open to all and which you can buy. All the optimization and adjustment algorithms, the team APItrade takes over. Service algorithms are not public and there are no analogues at the moment. Algorithms self-learning and modified in accordance with the behavior of the cryptocurrency market. The work is based on machine learning and has nothing to do with the classic bots and algotrading programs, everything is much more serious and large-scale. For inter-exchange arbitrage, the service has servers next to the connected exchanges, which allows to minimize the ping and speed of processing user requests.www.apitrade.pro/support.htmYou didn't even answer what I stated here.
If me and you uses the same bot with the same code on the same coin on the same exchange, we are probably going to have a fight against each other and to split the rewards, but if it's public and 20 more people will do the same, we will earn nothing.
Also, whats prevent you from using the customers funds in order to pump altcoins that you are invested in, even if you use the best algorithm around it's not enough to proof.
