Well, let me put it this way.
0.2% per day is 73% in a year before compounding. No traditional investment will promise to give you a specific amount
ever unless they are a scam. In cryptocurrency where the market is volatile, they are certainly a scam.
Now consider compounding. Your 5 BTC will not be worth 73% more than you put in after a year because it will compound each day. This means that in a year you will have 10.35 BTC, in two years you will have 21.46 BTC, and so on. If you were to leave your BTC in there for 20 years (figure out how to calculate compound interest), you would have 10,776,294 BTC, more than half of the amount that could EVER be created.
Does that sound like a safe investment to you? All the information that they give about it is that all that money comes from a "special fund".
When i closed investment, i got all of my coin and and also with interest. So far it still interesting and safe
It might pay you. It might pay you for quite a while. But sooner or later, it will steal everyone's money.
