Digital currency can be gone with the push of a button.
Who controls that button?
Please say who.
Or a really smart hacker or group of hackers. Perhaps working for a criminal organization or foreign government?
No I don't think so. Stopping the entire BTC network would require stopping every node, or at least a huge number of them.
Nodes get cracked all the time but not enough to even affect processing times. Exchanges get cracked, people get their wallets broken into, etc. but none of it happens on a large enough scale to make much difference. The motivation is there. Satoshi Nakamoto's wallets are still sitting out there waiting to be robbed of their ~$75,000,000,000 but no one has gotten them yet.
