Do not listen to the fiat/alt coin shills, they will say anything to push Bitcoin down. There is nothing that cannot be changed to improve Bitcoin, it is a piece of code after all. The only difficult part, is to reach consensus about these changes and when to apply them. < SegWit vs Classic debate >

You will always have people pissing in the wind, and telling people it's raining. ^smile^

Uhh, no. Seeing what bitcoin did to the current financial scene, it can't be considered to be a failure but rather a success even in its infancy. Also, it greatly helped people with restrictions on their respective countries gain access into buying things which they cannot, another plus to the economy, I'd say.

Bitcoin is a failure? of course no .. BTC is king  in the crypto world it is in the first place   in last 7 years and is strong coin ..  so from my view it is not fallure and wil be stable long time ....

I think bitcoin is revolution to financial system so lots of banks and entity don't like its concept of decentralization as that can ruin how banks are getting profit out of others money and paypal like processor can die because they just love the heavy fee they get on every transactions. Bitcoin will never die, will come up being more stronger with every new challenge.

bitcoin may have many problems on its way to success but this doesn't mean failiure at all. bitcoin is a new technology and anything new needs time to fix problems before becoming the perfect thing.

Well said. But how general bitcoin crowd can believe in bitcoin when sometimes even core developers are refusing to back it up?
I am talking here about Mike Hearn's rage quit. Imagine this situation - some newbie just joined bitcoin hype train, just to see that one of bitcoin developers is telling people that bitcoin is 'a failed experiment'.

Who is saying that Bitcoin is a failure? I don't know of any reputable source claiming that. Maybe it's the bigblock-fanatics making this claim? Well, those have been screaming for a while... if their predictions would have been true, the Bitcoin network should have collapsed months ago...

Despite the utterances of some XT/ClassicCoin altcoin shills trolling the Bitcoin forum, Bitcoin is stronger than ever! The number of transactions is constantly increasing and true innovations are being deployed at Bitcoin Core that will increase efficiency and security of the network. Also, the public perception of Bitcoin has improved somewhat - at least to such a degree, that banks want to create their own Bitcoin copies...

ya.ya.yo!

BTC is something unique. What else  can cost such an amount of money? I suppose it is definitely not a failure

How do You show me a potential of Bitconin with No Internet, No Smartphone and No PC?
Cash have no problems in this conditions.

Cash work even with Black Out case.

Exactly, negative people will always be busy in spreading negatives related to bitcoin and bitcoin is developing in the best way at a moment, and it will be a huge success in future too.
