Why bitcoin price decreasing, now the price is $9,346.22 !! what is the causes of this dump ? Also all of alt coin dumped.
Bitcoin doesn't have value because it uses a blockchain, Bitcoin has value because its cryptographically secure.
The only way that happens is if the blockchain is secured through cryptography.
While I'm not saying blockchain has no value, its certainly subordinate to that of cryptography.
Cryptography is what will "bank the unbanked", "give monetary sovereignty back to the people" etc.: blockchain is the tool that solves a specific cryptographic problem that stopped us from implementing a cryptographically secure currency on a global scale.
Cryptography has been used for millenia, not blockchain. We didn't have "blockchains" and suddenly invented cryptography to make them work.
Its not a "blockchain-currency", its a "crypto-currency"
Dr. Adam Back is a cryptographer, not a blockchainer.
Satoshi Nakamoto is\are\were cryptographer\s, not blockchainer\s.
So please, stop saying "blockchain" this, "blockchain" that. Blockchains are what suit and tie nerds think will change the world. Cryptography is what matters.
