Please keep me posted on how things progress on Hashflare for you.
How much hash power did you purchase?
Are you reinvesting the daily proceeds into more hash power or withdrawing it?
required hash rates could increase, or the company you're engaging could go bad.
These are the two main risks with cloud mining but it also appears that the price going up on the coin would more than offset the incremental increases in mining difficulty. It comes down to trusting the company you're dealing with to still be around long enough to make good on your investment.
I have a good amount of Vertcoin too and would like to mine it. It's easier to mine than most coins and is designed to stay that way.
only 150GH/s.
If my calculation is correct - it should take me 6-8 weeks to earn back my initial outlay - based on todays current BTC prices. If it is looking that way in the first few weeks i will likely invest further - so to answer your question - i'll be reinvesting if it is looking like the numbers add up to tell a good story.
I would love to mine vertcoin - i'm very excited about where this coin is heading - but they're asic resistant so it is likely that cloud mining companies wouldn't find benefit in setting up those kind of service. I guess that's the "drawback" of being decentralised.
