I really don't see what differentiates counterparty and mastercoin from other altcoins hence why I don't think they deserve their own subforum. As was already mentioned, putting your transaction data into the Bitcoin blockchain doesn't make your coin Bitcoin, it's still an altcoin. That doesn't mean those altcoins are useless, but they're not Bitcoin and they're not Bitcoin 2.0.
By the way, discussion about how an altcoin affects or differs from Bitcoin may be posted on subforums other than alternate cryptocurrencies, so discussions about blockchain bloat caused by altcoins are allowed outside of the altcoin section.
Read just this old topic. Can someone explain what then is Bitcoin 2.0, if not something like Counterparty and Mastercoin? Can you give examples what that have and what not.
"Bitcoin 2.0" is what altcoins call themselves to convince people that the altcoin in question is different from the thousands of other altcoins when in fact it is just another clone.
