Make sure you have reasonable expectations when buying mining contracts as they do not make you rich quick. You will most likely have to wait for sometime before you get your money back depending on many factors. It's just like the stock market as in it bears the risk. That said Minestore is one of the few reputable companies in the cloud mining game.
I think it's a good investment, I was studying the returns and I find them very attractive, I'd like to be informed about it. It is very simple to earn upgrade yourself and get paid on a daily basis.
I received my payment on time after getting upgrade my free package. I am very happy to mining with Minestore.
To be involved in this investment we need to be patient. Calm and rational thinking. Do not rush and do not be greedy..
