I thought I would make a big list of different ranges of Bitcoin investment sites or services along with a risk level out of 100
100 being extremely risky, don't invest
0 being 100% safe and 0 risk of loss on your bitcoins
Yet again usually the higher the risk the higher the payout

All sites below are crypto currency based (mostly Bitcoin) and includes most investment options.

1. BTCJam.com (Risk: 10/100, very safe)
Features for Lenders:
- up to 19.3%APR
- Advanced Borrower Identification and Rating system (face recognition with license is required, meaning a massive reduction of fraud/photoshopped docs)

Features for Borrowers:
- Quick verification process
- Low fees and interest rates
- Plenty of investors ready to find your next big Bitcoin idea!

My Investments:

3. PRCDice.eu (Risk: 50/100)
The reason why the risk for PRCdice is so high is because a number of things could happen:
- The owner could run away with investment funds (I doubt t, but very possible)
- Someone could get extremely lucky, win a lot and you will lose a chunk of your investment
But on the upside:
- Someone (like the other day Road2Wealth lost 200+BTC) could lose a lot of BTC making a massive return on your bitcoins
- Convenience of instantly investing and divesting your investments. NO delays what so ever
- Instant deposits and instant Cashouts

My investments:
#1 1BTC original investment, cashed out 1.08BTC after 24 hours
#2 Coming Soon
Profit: 0.08BTC from 1BTC in 24 hours
