If it helps to understand, cryptos are actually made to be viable while things are functioning semi-normally, just really really privately and out of direct control/regulation of the world's governments.
If you're like most people, you basically already do have the vast majority of your money tied up in something that doesn't exist other than on a computer: your bank account. The wrong file gets corrupted and the backups don't work? Good luck proving you had your 5, 10, 50, 100k in that account that got corrupted.
Crypto's are interesting to the average joe who doesn't care about the whole privacy thing because of the volatility. Generally, your US dollars only lose value over time because the Fed's gotta keep this easy money train rolling. QEternity and all that. Bitcoin, by contrast, can both increase and decrease sometimes in wild swings. This means you can "make" money simply by holding, assuming the coin you've chosen doesn't simply fade from use and never recovers its value.
