Yes it is unprofitable to mine. So less miners means the difficulty goes down. Then it costs less to mine. Then the price goes up by an order of magnitude a year after the halving like it did the last two times.
Then more people mine again, and the difficulty goes back up.
The problem with people involved in BSV is that instead of learning how blockchain work, like is old timers did way back in the day, you learn from Craig Wright, who doesn’t understand it very well. And he lies a lot.
Bitcoin was perfectly designed to make sure there are always miners. The lag between the halving and the price rise is large heavily invested miners capitulating, new players with cheaper or free electricity and newer ASICS coming online to take advantage of the lower difficulty.
I won’t be taking investment advice from kids with 4 figure net worth’s anytime soon mate.
