No Bitcoin is technically lost forever, just stuck in wallets or in private keys that are not currently accessible by someone right now. If you really wanted to, you could easily get away with finding them, eventually, after a lot of time and money is expended.
The only coins lost forever are those which are forked out of the chain.
Topic: How many Bitcoins are lost forever? - page 15. (Read 43090 times)
It's difficult to calculate how much bitcoin are lost. I'm sure there're many bitcoin users since the beginning until now who left bitcoin or lost their private keys.
Those bitcoin lost can't be recovered back unless the owner know his/her private keys. So, I guest it will be lost forever.

When I read the question first, I didn't think it was about lost private keys. Come on, there are many verifications (phone, email, secret sentence) which help even if you lost the password and stuff. I thought it was about burnt Bitcoins and how many are burnt already is an interesting question. I have seen the news about 2000 BTC approximately, but I am not sure whether we can believe it.
I've heard that someone had forgotten to remember the identifier and password when they had quite a lot of bitcoin, this would be very unfortunate, bitcoin was wastedWeb wallet?
Money are lost in a lot of ways, fiat currency or cryptos.
Hope one day someone can create an alt where missed money goes to some charity instutition.

I think it's very difficult to tell the exact amount but I remember to have read somewhere on the internet that it's about 4M
Maybe there isn't a big number of lost bitcoins but there is much big number of lost wallet keys and passwords, hard drive damages and etc, all this facts causes lost of bitcoin. We can't say specified number of lost bitcoins but there is some ways to discover it's nearly number. If person hasn't made transactions for 12 months or more, there is high chanse that wallet and bitcoin is lost. I think there must be some similar tools in blockchain to know number of lost bitcoins and that bitcoins must be remade because it's lost and lost things can be founded.
It is hard to know the exact number of bitcoin lose or forgot their wallet password.. this is just my speculation maybe we have 30% of bitcoin lost or forgot bitcoin wallet. maybe old people are die too and forgot to tell their love ones that they have lots of bitcoin in their wallet.. And i think many investors in bitcoins before are forgot their bitcoin because bitcoin is cheap before they are holding lots of bitcoin and forgot the wallet or send it to wrong address.. Unlike now that the price of bitcoin is very high or expensive the value is not the same unlike before..

Burn why they are burn bitcoin i think bitcoin is not the same as pos that burn coins every year.. Maybe halving that can reduce the supply every time halving is done. it can affect the value and increase the price. because the price of bitcoin is always depends in supply and demand..

I also think that there is always a way out of a difficult situation, and above all there are opportunities to get back into your wallet. Thus, this option is already eliminated. But there are times when people just stop using purse and lose sight of him, along with the content. But I can not understand how it burned bitcoin?

its not possible to answer this question until we just count all the old addresses and see how much balance they have un transacted for years . that can also be someone saving money for a long term investment but lets take it now as lost bitcoin which can not be recovered anyhow
It only counts if you deal with it will not work. The balance of almost every purse replenished depending on whether the user is active, but it does not mean that the costs are always a minimum or maximum. If you can spend it all.

Well i have just learned new things today/yesterday about some bitcoin addresses i had found something, Here are some btc addresses that receive bitcoins but these can't be spent, for more information about have a check at this thread https://bitcointalksearch.org/topic/what-kind-of-address-is-this-1168745
I do not know whether the difference is that they have lost and how many have lost. If coins are lost, it is the problem of those who have disappeared, and not from other users.
I guess it should be so many of bitcoin that lost forever around BTC1-100 as we don't know for sure, so just let us know how much it is in your opinion. Unfortunately, blockchain technology created so secure and give control to user of their wallet and no one could know how much btc inside even admin of blockchain. Moreover, there are plenty of wallet sites and we don't know which one that have been lost their private key, so no answer about this just lucky guess.
It is very hard to predict the exact number of bitcoins that are lost either due to misplacing the private key or by the death of the holder. But I believe a good chunk of the total number of bitcoins mined should have been lost because I have heard a lot of people telling that they lost bitcoins when they formatted their old hard drive or due to other silly reasons.
When bitcoin will reach its bottom and production stops, that's when you can already try to predict such numbers. But it probably will not be very significant, because then everyone will be busy counting their profits. After all, only the price will jump to the maximum.

Well that's a good question to investigate! I guess that is very difficult to know at this point because no one gave report if lossed bitcoin. I think that we will only be able to find how many BTC are lost after they are all mined. Or we can probably research the blockchain legldger and find a pattern that could lead us to see how many BTC could be outside of the. And many user forget wallet id so some amount is loosed in that way
This question generally can not find an answer, because how many people lost wallets, and with them the keys to their bitcoin, as well as those who have not learned to use, although the beginning of its activities still put. But still this figure is unknown.
Well sure, technically the Bitcoins are not lost until they get permanently burned. However, if you lost the private keys of your Bitcoins then it is very likely that they will never ever be transferred again. So those Bitcoins are acutally out of the "game".
They can be lost forever. For example, you have thousands of bitcoins and it makes you feel unsafe if you will just store it for a single bitcoin wallet. So what you did is you create another wallet for distribution of your some bitcoins and partitioning it. But as the day goes by, you forgot the private key of your account and as well as your email. So basically, the balance bitcoin on that wallet will be lost forever.
Can someone please explain me how bitcoin can be lost?
I don't feel they can ever be lost, losing the ability to access your wallet is the worst that can happen, but in reality the coins are still there.They can be lost forever. For example, you have thousands of bitcoins and it makes you feel unsafe if you will just store it for a single bitcoin wallet.
