Masari seems to be the only legit other cryptonote coin.
You're bordering on blatant promotion here. Come on.
MSR is ranked roughly #600 on coinmarketcap. It could have a great future and if so might become worthwhile to discuss as a direct competitive threat to Monero some day. but until then I have a hard time believing there aren't a good share of 600 others that are more relevant to this thread.
Smooth apologies. I hold the same legitimacy for Aeon as well. MSR appears interesting for the sharding, but haven't studied the design thoroughly yet. Not advertising the coin. I only meant to stimulate a discussion around the interaction of XMR with smaller, lighter coins, which could be the technical scheme required to face a large economy's volume of transactions; and its impact on the price, long-term.
