As said before, since CPU/GPU mining became unprofitable, developers created a new way of mining known as Cloud Mining.
Most of Cloud Mining websites are scam or illegal so be careful, dont invest on them because you might see your money lost.
Good thing about cloud mining is that, in most of them, you don't even need to have your computer turned on, so it's all profit. Mining in a cloud takes time - as everything - but no energy wasted, so your cost is only buy the contract to mine.
Usually, contracts are 1 year long, but sometimes you get 2-5 years contracts and even lifetime hashrate. Use them well ;)
One of the best Cloud Mining websites is HASHFLARE
HashFlare provides 1 year contract of SHA-256, Scrypt, EQUIHASH and ETHASH. Price varies according to the hashrate you want to purchase but the minimum is for SHA-256 or ETHASH and cost USD$2,20. Of course you wont get much profit with minimum Hashrate, but i think might be a start. Only way to mine in HashFlare is buying a contract.
HashFlare is a LEGIT website!!
As said before, other website that provides CloudMining is MINERGATE
If you read about CPU and GPU mining, you must know by now MinerGate very well! It's the one that has everything...and of course, it's LEGIT!
If you don't want to risk your money - it's ok, i haven't either in the beggining - there are always ways to start earn some coins. Next two websites let you start without investing. Let's go for them:
