Can this robot help me in trading?
It won't help you if you don't know what you're doing. Bots can automate the trades you tell it to make. If you tell it to make bad trades, it may even amplify your losses beyond what you might have lost trading manually.
So I prefer the good old way of trading manually
If you're more of a strategist you can automate your trades and that can be helpful, although your strategy needs to really be well thought out. Otherwise you're 100% correct, this can very well amplify your losses if your strategy is inherently flawed.
This might even work better in some instances that you as a traders lacks time in trading your holdings, you can use the bots to automate it, but even how good you are to strategist your trades, bots might still have a possiblity to fail, so even your bot is working, just make sure that you visit the trading history and always observe the progress that you and your gunbot is making.
