I have invested a little ethereum to try the service out.
[snip]
I have not tried yet and seen only the website. And I can say that I saw more tariffs than you say - 4 for investment (Beginner, Medial, Pro and Mine) and 3 - cloud mining.
Well, yes sorry you are right! As I said I find the site a little confusing for me so I overlooked the other two plans when writing the post.
There are four investment plans available now; the mining options are not available yet.
