The use of the word "successor" in the article title implies that Bitcoin is dead. It's a shame how many people (and news outlets) equate the failure of MtGox with the failure of bitcoin.
I dont think the subjugation of bitcoin to the past-tense is exclusively due to Mt Gox; the recent IRS ruling in the US of bitcoin as property also downgraded bitcoin's status significantly, at least in the US
Bitcoin the hype-machine is dead; it's now "just another cryptocurrency." The successor to Bitcoin would be a successor hype-machine.
