Go ahead and buy for the longer term, keep them safe in a hardware wallet for years before selling them. Nothing will happen to the bitcoin network as miners will not stop mining as long as there is some incentive to them or being the fees when sending a bitcoin transaction. There will always be transaction fees as long as people will keep using bitcoins and by the calculation the last coin will be mined to make 21 mln coins available in the year 2140, which pretty sure we would all be dead by then so do not worry as nothing will happen, except that the price may skyrocket after those years and you be a rich man back then when you will sell your coins.

You are so funny but make senses, lol

No, that's not it. What you're describing is a scenario where a portion of the miners stop hashing which makes the network more susceptible to such attacks. What OP is describing is a scenario in which all(?) miners stop mining Bitcoin. This is a very unusual and improbable case in which Bitcoin would most likely be going towards its death. However, let's assume that all of the turn on machines and nobody turns new machines on (also unlikely) the Bitcoin network would just come to a halt. Transactions would just go into mempools but they would never end up being confirmed. If you understand how Bitcoin functions, then you'd know that it couldn't work in such a scenario.

People are very bad with probabilities. This reminds me of people who worry about private key collisions when it is more likely that a meteorite wipes out Earth.

if the price getting lower even after halving happening the miners could possibly looking for another way to earn more profit rather than holding on bitcoin,just for example alt,but if they still see bitcoin profitable then why move,100$ will indeed make miners get away but even 300$ after halving will make miners thinking twice to continue the mining unless they got very cheap electricity

Ive worried at one time or another about every possibility that bitcoin could die for 1 reason or another but i think its pretty safe to say that miners wont leave. As long as theres profit to be made someone will be mining. Be that commercial miners mining dozens of coins a day or home miners mining a few satoshis each day.

The movement of chain will stop.  Automatically all transaction will be unconfirmed.  The Bitcoin economy will be in chaos.  This will result to fear and the buy support will start to be pulled out.  And then one by one cpu will start mining it again but due to global low hashrate, this will be susceptible to double spending.  But then all those who are holding BTC will make sure this wont happen so they will start mining it by themselves and the domino effect follows.  Basically mining Bitcoin wont end even if all coins are mined.  This is one of the reason, personal interest and investment security.  So be calm and hold your BTC for as long you want.

It's the way I interpreted the question. Nether mine nor your answer is incorrect.


Also im not sure I understand your second statement and how its applicable to what I wrote. Are you saying that there is a risk of this happening?

Theory: if ALL miners stop mining, as explained by Lauda, there will not be new blocks added to the blockchain, all transactions would not be confirmed. Panic! Value of bitcoin: zero.

Reality: that would never happen. Even if all current miners stop mining, the difficulty would drop in max 2 weeks. Old miners with old equipment would start mining again because it would be profitable again.

I think no one will do like that, no one will leave mining but only the small miners who will not earn good amount , there are a lot of other big miners who know well that mining is beneficial and they will not leave mining.
