Try to use cloudmining site but its risky 
yes...very very risky.
it is why i have programmed a system "about U2cloudmining site"
You have "zero risk".
all is absolutly free.
you claim shares for free.
you are the owner of the system.
you get the site's profit (dividends)
you can sell your shares if you are not satisfied for real satoshi.
Have fun...
