I fixed the image link. You make money, but the money you make won't cover the initial cost of the hashrate you are buying. So I am spending $138 but I will never get the $138 back because the difficulty will increase after 20 months making it unprofitable to run. After 20 months I make $134. I would assume at that time I can't resell the hashrate for much of anything. It seems like the key is to just buy and sell the hashrate.
After 1 year I would still be down $20, but I would hope I could resell the hashrate for more than $20.
If I may ask, how much did you pay for your 100 GHS and how long have you had it?
Very little I bought at 0.0001378 price so I only paid 0.01378 Btc for that amount. I am not a fan of mining but this time Hashnest sounded appealing to me so I gave them a try, it's only about 12 Euro in total.
Yes the key is in the trading, you should know when difficulty will increase and sell your hashrate a few days before it happens, so you can be in profit, but cloud mining is a very difficult game to come out on top.
Use it as a learning experience only and not a money making one.
