Anything that is consumer based is going to be expensive. My first entrance into this was a $700 computer called a Coinmine that Pomp was shilling back in the way. 

S9's are the way to go for $100 from us or less from other people. Repurposing industrial miners to produce heat and keeping 100% of the sats is a good move. When you get a heatbit, you are paying for something that looks nice, has a nice UI and is easier to setup. S9s aren't that hard but they're not pretty and take a little bit of learning to get setup

Beware of millions of ways to lose your Satoshis mining this bull market 

I already have a space heater that works fine. So I don’t need a space heater, but wanted an extra one to mine. The cost was near $200 for the heatbit and they were only going to give me 25% of the mined sats. Business model seemed weird and like I said the ROI would have taken forever
