Now I use the TradeSanta bot and it's ok to use.. I think that trading bots should be new boom of the market.
Are you sure about this? Why bots sell their bot then they know how to analyze the market, then, if they know they were focused on trading, not convincing weak people who have to get fool into their bots group. You may use trading signals as your reference on your research but don't rely on them, probably they had a delayed broadcast that might be putting your fund on risk situation.
Bots are used for information, we can still verify it through signals as well as watching the prices at coinmarketcap. Bots might not be that accurate but still gives a much faster and decent result.
