I have never tried using Grid before but most of the bots on telegram communities are not profitable after trading for more than 2 months. This means that the bots will soon become outdated and unable to update good market data, so they constantly trade errors. I used to join 2000 $ in trading pool traded by TCVN bot and now I have lost more than 500 $. So, do not trust the trading bots in community channels too much, use your knowledge to trade better.
