Down the road into a bear market what can a new miner except from a 500MH mining farm? How incredibly bad can this get? 5$? 8$? Asking those who are here before in 2018 so I can know what's awaiting me.
This below is the best advice you can get, other than that, patient is key here, although this is still pre bear market, expect the worse when the time comes, for now btc below 20k is very possible 60% chance.
One good practice is not to sell coins you have mined during a bear market, instead wait for the bull market and rip big.
