You accept risk? Still I would warn you with people who will suggest you to invest with their referrals. It's too good to be true and earning 100% within a week is highly not going to happen unless you invested to bitcoin at $8,800 then it will become $17,600 next week. Try to daily trade with those coins that has higher volume in the market and take profits when you gained 2%-5% this is safer, do and repeat until you make 100% gain with this strategy.
