You don't get the bot from him, he is just a reseller. The bot is developed by a team. The bot is a work in progress, it will have bugs. There are several versions of it. I run version 602 on windows. It works very stable, not one error, ever. We all get the same bot, so we all get a working bot. And you can always sell your bot at the marketplace if you feel it's not what you imagined. The point is, these times are not bot trading friendly, at least not with a small capital. You need to have a lot of money put aside to clear bags, and bags will happen, weekly. Successful trading will demand time, lots of money and engagement in a bear market.
