If Mining BTC Even with free electricity cannot pay the mining equipment in a year, that will be the doomsday of BTC, 2000$-2500$ is the limit.
I think that's not reason causes of bitcoin goest down at that price amount if you study the history of bitcoin in the coinmarketcap price dip at bpvery low value, so if bitcoin well down upto 2000$ well doesn't means need to panic and quit to invest in cryptocurrency.
