Give it a month when Bitcoin miners have to pay their monthly electricity bill.
Many miners won't keep up with the demand and have to sell their mining rig from losing profit because of electricity bills.
The Bitcoin mine owner should be able to adjust this by making initial calculations before mining Bitcoin, because if things like that are used as an excuse for them to no longer mine and sell their machines to others, of course other people will also think twice when they want to buy a rig. mining before the buyer uses it. So I think that reason is the wrong thing to say even though it can also be quite reasonable in order to be able to sell mining rigs that have been used before.
