Bitcoin robot? means bitcoin trading tool to make a profit?
If so, I recommend you not to use it. As financial experts have said, the crypto market is always risky and the nature of the market is changing very fast, so algorithms will not guarantee the situation of the market. Naturally, it will not guarantee good profits for you.
Bots can help because it takes emotions out of your trading. But if you want low risk, it's better to HODL.
But there are also some negative effects on using trading bot, especially if you are newbie on trading or just starting to trade. The negative side on that is you will become lazy if you fully rely on your trading bot and also the cost of trading cost, maybe the cost of the trading cost is extremely high, so rather that the cost of trading bot will add to your trading funds you end up having low trading funds.
But I really don't saying that using trading bot is bad, there's a lot of trading bot that you can get lessons, especially what @Bitmaxz said, you can add some of your trading strategy manually.
