Many cryptos with no use cases will die. some with bad technology like Ethereum will also die. When I invest in crypto, I look at the use cases, governance of the project and community. Cryptos like EOS, Bitshares and Peerplays will never die because of their governance structure. They're built for the future.

Governance is key, people don't even think about it but you must have a say on the direction of the project. Otherwise, someone will make decisions that benefit them and make profit from your investment.

My opinion.
