Or beanie babies. That would work as well.
Catching your sarcasm here...
While I agree, it's a high risk basically gamble, this is completely different than beanie babies because:
1. Cryptocurrency has made many millionaires in the last 3 years.
2. It's a technology that you're gambling on being adopted.
Beanie babies might quadruple your money 50 years from now. Crypto might return 500 times your money in 2 years.
Worth the gamble with a grand to me.
