I personally think that mining to obtain cryptocurrency is a brilliant idea, as opposed to purchasing.

If you were purchasing cryptocurrency to hold it, then we can only say that mining is a savings machine.

Now if you are looking for profit, I think it isn't a good idea to go with ethereum. Go mine litecoin with ASIC(so you can switch to bitcoin incase anything happens and you need a steady stream). Mining litecoin at current prices and hashrate with an ASIC L3+ is around $1400 a single month. If you want your mining to be more stable and less time consuming, check out giga-watt.com. You can purchase your equipment from them and then send it to their facility where they do all the legwork for you and you just sit pretty while making some tokens.
