Thanks. That's what I thought, wanted to hear if it looks suspicious for other people too. Their long time of activity confused me.
Nowadays cloud mining companies are fully transparent with their hardware etc or shady, hiding it's incopentence as it's in this case.
When I visit the site recently, my browser said 'unsecure' although their use SSL. It's fishy for me and I'm not recommend to use their service or even access the site.
About cloudmining, mostly is shady. If there are trustworthy one(proved their hardware), usually your profit is not as expected, the reason is the difficult of mining increase and their electric bills is not fully transparent.
