Read the main post once again, it seems that you do not understand the main idea of this topic. The one offering the 3% daily profit is not the site, but the dev of the bot. In simple sentence, this topic is offering you to invest on their bot. It means that you invest in a user (owner of the bot) who will use the invested to gamble on the site, not invest in the bankroll.
You don't get my point. Okay no problem, so you mean I need to invest in the bot then the bot will manage my money and invest on different things and the bot will get 3% daily profit while I get nothing, am I right? I don't understand who is crazy here...
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.
