Will you be excited about that?
What if BitOffer Quantitative Fund can make it?
Don't say it is impossible... You don't know how a quantitative team can do to arbitrage from the bitcoin market which is full of volatility.
Your post is ambiguous. Even if what you're saying is true which is very unlikely, many would still tag it as a scam just because you didn't explain well enough. You should know that, with a post like that this, there will arise several questions such as
* is the 20% fixed return on a monthly or yearly basis?
* what exactly is the investor investing?
* if you promise 20% ROI, what then is your gain from all these?
I think if you explain well enough, you might be able to find some interested peeps.
Concerning guaranteed money, I do not think there's any guaranteed money anywhere. Many have promised such already and it only ended as a scam
