I think the best thing to do now for someone that want to try mining ether is by leasing a rig (let me explain why). You invest much less to get some mining return, VS having to build a PC and try to find GPU that are NOT OVER valued. Also, when renting, you are not contributing at upping the hasrate, and then the difficulty, because these rig are already mining ethereum when they are not leased.
The biggest rig leasing place is the nicehash, but you cannot lease hashing power there. Is there another one?
dont waste your money with cloud mining either mine with your own hardware or stay out
think about it why would they lease you hashrate and not make a profit off it ? That in turn eats into your profits from the contract and you end up snake eyes.
