What if the price of BTC is now 400k at the time?
I said to myself, even that 1.5BTC per block will worth fighting for.
It's all about the value or am I wrong?
I will keep mining still and accumulating Bitcoin before that time anyways.
The miners don't see Bitcoin the way you view it, Bitcoin price has went to $18k and crashed to $3.5k and most of the miners never left even when they were mining at loss, it's more like unrealized capital loss on their investment. There are some some old miners that are still holding their block rewards of 6 years ago and haven't sell. If they didn't sell any of those Bitcoin when the price went all time high, nothing will compel them to sell or stop mining if Bitcoin price isn't sustainable.
Beside, big mining companies don't jump to start mining and expect to use mining reward for production cost, they raised a significant amount of money before they start the business, they know this kind of things is possible, so they get prepared with enough funds to sustain the business until the price recover when they can sell to cover up the future running cost.
Somehow this still backs my point up
"There are some some old miners that are still holding their block rewards of 6 years ago and haven't sell".
All miners are not the same, some have to sell their Bitcoin everyday or week even after they settle their electricity bills, they are not in for long term holding.
There are miners who believe that their present Bitcoin value can be 15k but the future value will be 150k so they hold it like their lives depends on it.
Bitcoin price crashing should be expected as a Bitcoin miner.
Thanks for your point, I get it still.
