When the Bitcoin value drops to $ 1. Is anyone else digging anymore?
Many times I wonder if the value of Bitcoin is due to demand?
And if the value of Bitcoin today when I'm writing this article ranges from $ 3300 - $ 3500. But if the current crowd is still selling Bitcoin and its price goes down further, the cost of digging will not offset the selling value. So who else digs for Coin?
If by digging you mean mining then yes. Mining difficulty scales so other than for short periods of time, the cost of mining should always be less than the cost of bitcoin. For that reason even at $1 people will be mining. Same answer for your second question.
If price drops below lowest mining cost, people stop mining, mining difficulty lowers, mining cost lowers, people start mining again.
There will come the opportunity again. Many people can buy everything at lower cost. If everything is cheaper, hopefully that it is the start for a new beginning on trusting the coin that it has power to increase the price again. People are going to stop digging but continue it when they could gain from it.
