Option 3: Invest in the gear and build your own ETH miner. If you spec it right, you can mine any crypto that uses GPU miners. A typical rig has 5 or 6 GPU's (rig cost about $2500 USD) and each GPU produces between 25-30MH/s It should pay itself off in around 6 months. (even after the expense of hydro is included)

If all of the GPU cryptos tank, you can sell the gear you bought, or have a very decent gaming computer.
