Sometimes, I don’t wish to venture into imagining the impossible because this my friend is an impossible.
All Bitcoin been mined and lost… just how would that come to be? Maybe you think the government would eventually becomes so obsessed with the conspiracy theory of having to buy all the Bitcoins little by little, store them all in a wallet and dish the private key or seed phrase to it…

If this be one means to satisfy your phobia on either Bitcoin would be around to serve as a currency of the future, well, no one could give you that assurance. Understand that it isn’t risk free, don’t be sacred to dive in with a plan and hope your ability to take calculated risk rewards you.
