Because they are cleverly concealed scams..
I've been on this forum for about 2 years now, I've never been accused of scamming some one. The people I've worked with will always say you that I've paid what I promised and I got proof of that. Please provide feedback instead of saying something totally clueless. You don't know me and we never did business with eachother. Just because you are saying something without any evidence makes me trust you less, say what you know for 99.9%, don't just say anything to fill up space.
Okay, fair enough, maybe my comment was too harsh and I should have said: "Because they are probably usually cleverly concealed scams..".
I did not mean to say this one definitely is a scam.
Just getting weary of what seems to be becoming an emerging trend, "We will do all this cool stuff, just give us ___ BTC". IPOs that offer nothing first other than a good idea and a list of bullet points are essentially asking for funds (in this case one million euros, not a trivial amount) for just that - an idea and a couple of parameters.
Most investors in my experience will say to you, "You are trying to sell me an idea for one million euros, but you actually have nothing yet - no code. If I really liked the idea why wouldn't I just go and do this myself? You are essentially asking me to invest one million euros in you, and I don't know you."
