I am a big fan of Hasflare but reccommending them now with your own referal link is just cheap!
At the moment no inverstment in cloud mining can be proftable due to the low exchange rate. The only one earning is you on the cost of others!

Of course cloud mining with Hashflare might become worth it again (especially fo those who can't afford antminers) if the cryptos recover ... but right now recommending an inverstment is not fair to newcomers!
