The failure of crypto communities to shunt their coins from the speculative-currency phase to the transactional-volume phase has been a tragedy
To be fair, it's because crypto in general is:
1. Almost impossible to understand and use for anyone that isn't a techie;
2. Accepted basically nowhere without cumbersome third party intervention;
3. Too volatile to be used as a store of value;
4. Uninsured against theft or loss;
5. Not sufficiently superior to established systems at anything other than a) instantaneous international transfer (not useful in 99.9% of transactions to everyday folk), b) low-fee transfer of huge volumes of wealth (not useful to 99.9% of everyday folk; also see point 3 above).
Right now crypto is a very poorly implemented solution looking for a problem to solve for everyday people. Until that happens (if ever) it will remain a niche speculative interest.
