I tested both versions of the program and am currently using the paid one, planning to add extra modules. Overall, the bot is impressive. It can be used for manual trading, but it performs best in auto trading. If you work with exchanges like Binance, Bittrex, or Huobi, definitely try the free version. You can later switch to the paid one. I chose the paid version for the following reasons: - No limits on order size. In the free version, you can't place orders over $40; - No limits on the number of active trades. The free version only allows 20 trades. This isn't as critical for manual trading, but it is for auto trading; - You can trade across all pairs. The free version is limited to pairs with Bitcoin, while the paid version allows trading with stablecoins, Ethereum, fiat, and others. The paid terminal also offers several interesting features, such as running multiple copies of the bot, but they aren't as important. However, the lack of limits is really useful. I'm also considering adding a scalping module; I want to see how the bot will work with several interesting strategies. Overall, the bot is fantastic. It makes it easy to place orders, analyze charts, and so on. Everything works as it should, and there are no significant differences between direct trading and using the bot, except that it's much more efficient through the bot.
