When Bitcoin gets to a stage where the mined supply is basically 21m (that is, very little remaining btc left to be mined), will Bitcoin still remain a secure network?
all 21m btc will be mined in 2140 , thats 119 years from now .
that time the computers are now super advanced and who knows maybe they can now be able to crack btc private keys ? but thats is something thats not our problem anymore because i think that we could last that long and if ever our lives .
The security of Bitcoin depends on whether and how many people are using Bitcoin, that is, whether transaction fees are sufficient for mining activities. As long as people use Bitcoin, it will remain fairly safe.
it is ? well we have nothing to worry then because the btc users doesnt go down but it only goes up and when more people are using btc ,
the value and the mining fee are also going up .
