My favorite service for cloud mining is definitely HashFlare, and it's crazy easy to do. You can pay with a card or with BTC. It's most profitable for BTC mining right now, but LTC is also profitable. I currently have 5 MH/s ETH and 50 GH/s BTC. I've done a total of 7 withdrawals, and they're very fast to process them, too! Here are the current numbers for what you can expect for returns from HashFlare
| Investment | Hashrate | Total mined through a year (All numbers taken from CryptoCompare) |
|---|---|---|
| $15 | 100 GH/s Bitcoin | $43.73 |
| $150 | 1 TH/s Bitcoin | $437.30 |
| $750 | 5 TH/s Bitcoin | $2,185.03 |
| $37.5 | 5 MH/s Litecoin | $42.69 |
| $375 | 50 MH/s Litecoin | $426.91 |
Bitcoin mining is obviously more profitable, but diversifying is never a bad idea in Crypto. Let me know if you end up trying HashFlare! (Disclaimer: that's a referral link)
