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.
Agreed as well, even though Smooth has never tried to stimulate conversation about his project over in this thread or other coin threads... so you have a good point about how they probably hold the same legitimacy trying to "tweak" some things to practically the same codebase as Monero to make them more "lightweight", he never goes around and tries to "preach the word" to other monero people here or anywhere else besides explaining his viewpoints on the Aeon rebase over at /r/Aeon or over at the other Aeon threads here on Bitcointalk.
