That's a great news for both Bitcoin and counterparty.
Then why did counterparty sick like a rock on the news (after sliding for more than a month). btc's dead.
I think this dump was caused by counterparty leaves overstock, not the restore of 80 bytes op_return.
Are you sure this dump is not more scary of that sidechains will make all what Counterparty and Mastercoin promise? now are excellent place buy more. Or jump out from sinking ship

if price will go little more lower who even want to buy XCP? Then XCP no have any value and anything not really working atm, no desktop wallet, no smartphone wallet and even anyone no are doing it? not even any screenshot of wallet what have make few month already and launch have been after few week again and again and same time webwallet have standing in same point really long time and looking 10x cheaper than NXT wallets, only promises about smart contract, medici which have only IPO or something over XCP if even that...?
Even Mastercoin have go more forward last months (if behind public information no have happen much with Counterparty) and maybe that working already better than Counterparty?
We must still remember if there will come good news and sidechains can not do what Counterparty can or doing better that price will go really fast and really high.
