Do you think that cloud mining at all is not worth it? I think Hashnest mining may be profitable, because you can mine, and you can sell your mining power at some point. It's like a stock market - getting dividends and trading your shares. But in mining your dividends may be higher than 100% annual.
If you look here
https://www.cryptocompare.com/mining/#/contracts you will notice that most of the contracts never pay back. The best contract have almost three year payback time at current conditions. It will probably never pay back as well.
Better to buy some bitcoins or other tokens.
Yes, but I believe bitcoin mining at Hashnest will pay back, however. And, of course, better buy litecoins and other forks than mine them in cloud (or mine them at home).
