I came across a news report about profitcoins.io and now Im wondering if I should invest some btc there or not. What do you guys think?
Absolutely not. You can smell scam and see huge red flags from a mile there. But I do not need to tell you anything else, just talk to this screenshot:

What do we see here?
1. A promise of
DAILY gains of 1% isthe first red flag. Simple logic test: if they could make that much, why would they need your money? If this product would work, why can't they get millions of dollars just this working product to some financial corporation to raise millions or simply sell the tech?
2. A progressive scale of return based on the investments amount. That is not necessarily a red flag, but it becomes one, when you check numbers (they are almost doubling from tier to tier). It is very likely a Ponzi scheme.
Also, there are unsupported claims of some Patents (can find any patent issued for their UK company),
And, even though they claim some UK founders, this project is likely from southern Asia. Just check their marketing thread with fake "reviews" on Quora:
