Those who have put their money in Bitcoin defend it with a religious fanaticism, I have found. They delight at how much money they have made from, not nothing, but very little. But, all fanatical cults inevitably come unstuck.

From what I understand crypto-currencies such as bitcoin are “mined’ using mathematical algorithms. China had made advances in quantum computing that will enable it to have one million times more computing power than all of the computers in the world today, meaning that crypto currency security, and any other sort of computer security will be gone.
The West has been more concerned with political correctness issues such as transgender toilets, and thus, unless it regains some degree of sanity, and gets down to some fundamental R&D, will vanish from this problem, alone.
When I put this objection to a young guy who had sunk his money in Bitcoin, to his credit, rather than wasting it on the things we all wasted our youth on, he said that the objection would lead to a collapse of the entire system. And, he is right. But, this time it is us in the hot seat. That is, if the Russian’s “Satan2” missile, capable of obliterating an area the size of France, and which is set to be operational in early 2019, does not get us:
