The next project to be aware of must be teleportation,
When quantum computers are active a new problem with hit the lights.
You would be able to observe things that you could not even begin to imagine observing or altering by mechanical manipulation.
It's to early to say Bitcoin would be safe.
I think as these technologies develop, so too will crypto. People will figure out ways to prevent hacks due to quantum computing/teleportation, etc. The real thing that threatens cryptocurrency adoption are governments.
See, if governments decide they do not want crypto to exist, they will simply block the major exchanges and Bitcoin-related sites and before you know it all your hopes of Bitcoin becoming mainstream will vanish.
