Please take a look at BitcoinVest, a mining supplier from Germany, based near by Frankfurt am Main. Look at the imprint (Impressum) on their webpage. I have been there since the beginning of September 2017 and I can say that it is one of the best, most serious and stable providers on the market. He also pays continuously. There is no mining fee! I am firmly convinced that it will be very worthwhile and further worthwhile. You also buy only lifetime contracts. BitcoinVest fares beyond Genesis and Hashflare in my opinion! Their contracts are also limited to 2 years or 1 year, BitcoinVest contracts aren´t.
Here is the link to the website: https: //www.bitcoinvest.de/? Refer = 4656
Take your time and do your own research. That's very important. I am not an investment advisor. What I say about BitcoinVest is solely my own opinion. If you have questions, please ask me. Good luck mining and maximum profits.
