Getting into Crypto

The buy-in for a mining rig is way too high to make decent money off of it now. Not having to pay for energy consumption is fantastic, but you aren't going to be seeing huge gains unless you start mining a coin that has a low difficulty level, holding onto it, and then selling it once it goes up in value. It's essentially gambling/playing the cryptocurrency market but investing in a coin with hardware and your time instead of money.

If you're looking to make money, you'd probably be better off just day trading on exchange websites. It may be a good idea to mine something to get some coins to start trading.
