Whoever offers 3% daily profit is never trustworthy, no matter it's site owner, bot owner, the bot, or even investment god.
Simply you dont the point of the topic, it is simple to understand but you are the one who are confused with the main point. Dont make it hard, you are offered to invest on the bot and the bot will give you 3% daily profit of your investment.
Simple example, if you invest 1btc then you will get 0.03btc per day. Surely, everything that gives you guarantee profit is suspicious and should not be trusted.
