... If you know, there are only 21 million total Bitcoin that can be mined. Once the miners have opened up a lot of Bitcoin, the supply will inevitably run out, let alone the Bitcoin protocol changed to get a larger supply.
Well, the question is, what will happen when global Bitcoin supply reaches its limit?
This question has been answered thousands of times, but there is so much misinformation in the replies, I feel compelled to respond.
First, the supply will not run out. Bitcoins are not consumed. The money supply will reach 21 million and stay there (except for the small amount that is bound to be lost). By the time the last bitcoin has been mined, the price will stabilize as adoption reaches saturation.
Have you heard of supply and demand? If the demand for and item goes up, while the supply remains the same, ...
If it reach it's limit the demand for bitcoin wouldn't stop ...
The demand will not go up for ever. I assume that in 100 years, adoption will have already reached maximum.
When BTC has touched 21 million, then Bitcoin can not be mined anymore. Then the BTC price will soar to the moon. The BTC holders will get rich suddenly. We'll see later.
Bitcoin production is slowly going to 0. There is no reason for the price to rise suddenly.
When we reached 21 million supply limit then there will be a shortage in supply.
I agree, I think if bitcoin is getting scarce ...
Bitcoins are not getting scarce. There will be no shortage. When the supply reaches 21 million, there will be 28% more bitcoins than there are now.
The answer to this just lies in the supply demand paradox. As soon as the supply is cut out, block reward becomes nil, then this will force upward pressure on prices ...
When no more bitcoins are mined, the block reward will consist of transaction fees only. The supply will be constant, and a constant supply puts no pressure on the price.
When bitcoin supply reaches limit,still demand would continue.But there will be a big shortage in supply of bitcoins as every one holding bitcoins would be never ready to sell their holdings.
There will be no shortage, and saying that "every one holding bitcoins would be never ready to sell" is silly. There are plenty of people selling now. Look at the volumes on exchanges. There is no reason why there won't be plenty of people selling in the future too.
