No need to apologise @stover.daniel

You can check profitability on various web apps, but ultimately you need to take the same approach to it as anything of this kind. You invest what you can afford and use it as it should be used.

In the case of cloud mining, you should invest no more than 5% maximumof what you would like to invest in your cryptocurrency portfolio in total.

You might buy some coins cheap or exchange at good rates, but all the time, the small increments the mining will give you, will help you earn what is essentially interest on your original investment, long-term.

In the case of an x11 contract, you should see the first 5-6 months get you back what you put into it (if you're only mining Dash and the price remains stable). As you get a 2 year (no fees) contract, that gives you 18 months of profitable mining.

You won't get rich quick and it may slow down if mining difficulty increases on a certain coin, but you should slowly grow your portfolio with minimal risk (5%).

I hope that helps.
