Dear Sam, Other wise investement is genesis mining contract :
I have invested a total of 810 USD mid of april in 2 years contract and received already a total of 431 USD

DASH (x11) contract : for 207 USD (using my 3% code : 3q8sux )
you will receive daily about 0.0045 DASH (=0.72 USD)

For ETH 4MH/s (120 USD) you will receive daily : 0.0018 ETH (= 0.56 USD)

For BTC 4TH/s (559 USD) you will receive daily : 0.00113662 BTC (=2.84 USD)

of course the income declines about 10% every 40-50 days with the mining difficulty, but you will receive more than invested, and much more if the coin value increase.
