I have read several times here that claiming bitcoin is dead. As what you can observe, bitcoin is continuosly growing each day. It become adopts by many usually because of its fluctuating price. The demand is high, the massive adoption has been increased indeed. So, I can say bitcoin is really alive to its finest.
As I write this, Bitcoin is selling at $1135.25 after having going down well below $1000 couple of days ago, is that the sign of something that is dead or even dying? For how long would some people remain blind to the fact that Bitcoin no army can stop an idea, whose time has come. All the stumbling blocks won't stop Bitcoin, if anything they would make it more resilient.
When mt.gox closed and bankrupt I also consider bitcoin is dead, but the fact is bitcoin still up and continuously develop innovations. This is because of what? because of high level of trust from community that they have. there are 3 big news for two months, starting from SEC decisions, then take a hit from hardfork issues, things that are repelling the price level bitcoin, but then came positive news emerging from Japan, they began to apply bitcoin for public activities in their country.
If there are people who always say Bitcoin will die, he/she must try to divert attention to altcoin, where altcoin will die earlier than bitcoin.
