LTBCOIN (rewards coin for LTB) is held in nearly 5,000 wallets and there has been over 180,000 LTBCOIN transactions to date

OCTOPARTY used to be an alt-coin, but they decided to abandon their chain and become a counterparty asset instead
SCOTCOIN did the same thing as OCTOPARTY
Counterparty has over 20,000 assets registered and nearly 300,000 transactions so far. Far more activity than the various colored coin flavours, coinspark, mastercoin/omnicoin etc…
Symbiont recently raised $1.2 million to build their smart securities platform (also see the OP of this thread). These are the guys who created Counterparty, and they have stated multiple times that they are dedicated to counterparty (although they have also stated they will be working with other protocols - but that’s fine, there are trade offs and benefits for each system)
At the recent American Banker Digital Currency Conference, Symbiont was one of the main sponsors, and representatives from symbiont/counterparty at three of the talks. Notice how there is no one from open assets or omnicoin etc.
Lots of other projects which can be found here
Several tokens which are redeemable for various goods and services, such as pounds of coffee on the blockchain, those bitcoin keychain images you see everywhere, store credit on BitVPS, professional audio composition services and more
There is already at least 3 startups focused on building infrastructure and applications for Counterparty, including Vennd.io, CoinDaddy, and of course my company Tokenly. Also, there is four wallet implementations (1 [2] [3] [4]) and two block explorers (1 [2]), as well as support on BlockTrail
Keep in mind Counterparty has only been around for a year and a half.
