Certainly makes it easy to have a high-density, high-value object - much more dense than casino chips. Put the only copy of a wallet with tons of BTC on a microSD. Fun marketing gimmick, too. Put $100 worth on a bunch of micro SDs, spray 'em gold, toss em out at concerts or stuff.
Would totally get headlines if someone put $1M worth on an SD, then laughed and ate it live on TV and said good luck finding it. Or tossed it out of an airplane, or boat, etc. People show off wealth in all sorts of ways...
I'm super interested in making cryptocurrency printable and exchangable.
It would be cool to make coins out of bits of recycled computer chips and resin, and only allow the e-waste recyclers to mint them. The global poor become our new bankers. ='D
