Mining of 1 Bitcoin costs $6000 on average so going below that price will be hard to achieve.
That's why I really hate mining bitcoin since it costs a lot and the difficulty to mine bitcoin is just getting ridiculous in daily period.
Mining Bitcoin doesn't cost a lot however if you want to profit you need a lot of money. Mining a whole piece of Bitcoin could cost more than $6000 depending on the time, which miner you're using and the electricity costs is different from each country. The increased difficulty is actually good imo as it balances out the price of Bitcoin in some way.
