Blockchain is a good technology which will find many uses.
Cryptocurrencies are just products made using the blockchain technology - products that is failing to get any kind of meaningful traction after the bubble burst
Cryptos need blockchain (they are build from the blockchain)
Blockchain does not need crypto at all. More and more companies are developing and using blockchain solutions which do NOT involve any cryptocurrencies at all.
Fools who believe the blockchain means that cryptos will also succeed are mistaken. They often point to the internet development, but completely misunderstand it. The internet was a good technology with many applications - but many of the products put on the internet during the dot-com bubble also completely collapsed because there was no meaningful business behind it. The strong ones - like for example Amazon - had solid business ideas based on normal people's needs and behaviours.
Cryptos clearly do not match needs and behaviours, and will therefore fail just like the more idiotic things that were put on the internet in the 90's.
The internet of course survived and so will blockchain.
Cryptos will die like many early failed ideas on the internet.
I keep hearing that but is it really true?
Both Taleb & Friedman have both demanded "Show me one sucessful business model or utility spawned form Block-Chain", and nobody can find one.
Sure you can argue that BTC proves block-chain is successful, but doesn't prove shit.
'Block-Chain' is a religion, and people here don't have clue what it means, there is nothing novel about a linked-list, they're as old as data-structures in CS, there is nothing new about hashing, there is simply NOTHING NOVEL about Block-Chain or BTC, what wasn't known long before Satoshi released his source.
Certainly a time-stamped model of P2P, where say everybody who ever downloaded a torrent and their IP went into a block-chain, 51% verified because real de-centrailization. But the fact is the existence of such bullshit would not be by any definition a success.
In fact for other than GOVERNMENT, its not certain why anyone would want a public-blockchain, ... and for private, there are still lots of database algo's a hell of a lot better than BTC, in fact the reality is BTC doesn't even work without a database (SQL) doing the actual heavy lifting.
So I concur with you that BITCOIN is a PONZI and its value will go back to zero, but BLOCKCHAIN will also go back to the way of the dodo-bird, because it means nothing to computer science people, it only impresses high-school kids because its open-source, and quite possibly where they 'cut their teeth on C++'
Saotoshi was a MATH guy, which is why most CS people barf at his code, and especially after 1.5 where CORE turned it into a pile of spaghetti shit.
