I am new to this whole bitcoin thing and know very little about it.
A few days ago I got added to a Telegram group which is run by a bitcoin & binary trader.
I am being proposed 100% ROI, with the trader claiming 95%+ success rate.
If I invest $500, I will get back $5000 within 5 days.
So, my question is – how do I know if this is legit or not before investing?
Their fees would be 15%.
