Don't you think it's fast enough already?
It's a currency that didn't exist 6 years ago, and had no help from any government, and now it's the most valuable currency in the world, worth over 200 times the global standard U.S. Dollar.
No I think the evolution of the protocoll its way to slow. As i wrote in the opening post, when programmers know for a serious security bug, but can't fix it for 2 years, because they had to fix even more severe problems first, then something isn't going so well.
What goes well is the building of the ecosystem and apps/services based on bitcoin. Probably coinbase which is just an exhange with a wallet has 5x the Programmers as Bitcoin has.
And that comment that bitcoin is worth 200times the dollar is total bogus. There are bitcoins worth 3 billion $ in Circulation as of this writing. Just the debt of US government (not corporations, or citizens) is 17.000 billion US dollar. That alone is over 5000times (!) (yes you red right 5000 times) the entire worth of all bitcoins ever mined. Bitcoin is really one of the tiniest currencies in the world. And the only way to change that is to become better...
