Trading bot is useless without a proven trading strategy. I spent some months on developing-testing-developing-testing a trading bot and there were a couple of nice strategies but in September 2017 Bitfinex and Kraken API's were upgraded and there were so many bugs in their work and no support from their techs at all... I understood that even if my trading bot is performing good I am not safe with that irresponsible and unprofessional monsters - exchanges(((
