NEO and IOTA have this unique approach to the blockchain by using DAGs that require no fees to operate, among other benefits. Are there other similar coins that are flying under the radar that can have a good bump in price in the near future?
Im pretty sure NEO is not a DAG, I think its a delegated proof of stake (where gas comes from) which is a blockchain not a directed acyclic graph.
Raiblocks was the first DAG out there, they have since re-branded to NANO, not really under the radar though....
Even if you found a coin with a small market cap that had a DAG its not guaranteed a good price bump, some people argue DAG systems are not blockchains anyways. Even IOTA has doubts from big hedge funds if the system is secure.
