I was just reading the news this morning and came across an article talking about the recent leaps in quantum computing.

I then started thinking of Bitcoin and the potential issues it could have with the program.

Since quantum computers go at an incredible fast speed I imagine they can double spend, making Bitcoin useless. I know very little about the technicalities of Bitcoin, and I hope im wrong, but will Quantum computing destroy Bitcoin?
