> - Are the valid use cases (other than drugs, ransomware and speculation) worth the valuation? I think it's fair to say that the current valuation of cryptocurrencies have nothing to do with their tech or use cases. These markets have the same signs as the dot com bubble. However, there are valid use cases if you're willing to search for them. One of them is decentralized DNS name registration without third parties like GoDaddy or ICANN (https://handshake.org/ https://handshake.org/), though this is a market, not a currency per say.
