This question has been ask many time before but here's my opinion about it , I only think of one possible thing for it to survive — It's demand will rise even more which means greater price due to the limited supply. However, I am doubting that we will choose to hold an obsolete coin in the long run, I do believe that time will come will people lose interest into this thus price will fall down very hard and we tend to find another coin we can rely on which is either the second placer (eth or xrp) or another fork of btc.

Nonetheless, don't worry guys. We're still far from reaching that point, just continue enjoying the benefits we could get from btc and make the most of it while it lasts .

The primary factor that determines the price of bitcoin is the law of demand and supply. Assuming that by the year 2140 all the bitcoins are already mined, supply will decrease while demand will increase resulting to a significant increase on its price. Now that there are no bitcoins no mine, miners would simply maximize their profits from transaction fees.
Currently, the price of each transaction depends upon the current price of bitcoin in the market. I doubt that miners would abandon their work but expect a fewer people engaging into this kind of business.


That is actually true. No more coins to mine but the compensation would shift to the transaction fees paid. Assuming that the price of bitcoins increase in the future (which would inevitably happen), transaction fees would be their saving glory in order to compensate high energy fees.

Equipment price will always depend on the ROI more or less. On average, the price set by most ASIC manufacturers is equal to around 1 year of ROI (maybe a little bit more) to get your invested money back. Right now, the difference is that someones ROI is extremely depending on their electricity price. While the price per mined BTC is low and you have to pay the electricity in USD a big part of the mined BTC have to be spend to pay electricity costs. A different solution would be to produce your own (renewable) energy and use it for mining.

The ROI-based ASIC-prices are also a reason why people who bought miners back in late 2017 early 2018 have now huge problems to get their ROI by mining that they've invested in miners. They bought them when the ROI was very good but since then the price of Bitcoin went down and the difficulty went up.

Although many of us will not see it as the event is expected in approximately 40 years, I am sure, Bitcoin will survive. Moreover, its price will be great. If our children deal with this crypto, they can be rich.

I am sure there are many scenarios they took place at inventing a bitcoin. Sure some unpredictable are still in place. But nevertheless, the fork is still in place to make more coins.

But I think we are still far from this point The closer we are higher the price of BTC.

Is year 2140 close to you? All of us here today are dead by that time and why do we care if we're dead already? Let the next generations solve it. Bitcoin will survive. But I'm not sure if Bitcoin will still be in the top spot. There might be a better one on it's way.

I think that every difficulty will have an expiration time. The expiration time posits that , there are always solution. In this angle, I'm sure bitcoin will increase because there will be high interaction of demand and supply.

In effect, it will lead to increase in the usage of other established coins and that will be a growth in the system of crypto.

I think we don't really have to overthink it.
Basicaly the miners would still get profit from the transaction fee's so they would still earn.
And the demand would be high so the price per Bitcoin would grow since we already hit the max supply.
And I think once the price of Bitcoin rise up the transaction fee would also increase so the miners would also have a good profit.

Of course, he will survive, by that time he will be on a par with gold and cherish due to his shortage, because he has a limited number of coins in circulation, only 21 million + the support of institutional investors will greatly raise the price

Don`t you think that it will be replaced by other blockchain platforms with more advanced technologies, and remain only as a historical relic?
