Re: Will Bitcoin be replaced by another cryptocurrency?
Yes it could happen but i doubt very much it will happen the short to medium term, to actually make bitcoin obsolete would be a achievement.
It would have to offer something very important for mass adoption which Bitcoin doesn't offer.
Transactions that confirm in a minute?
Seriously, mass adoption means people actually use it for their shopping. If you send coins but the vendor doesn't receive them, then you are in limbo - some ordinary people will even accuse the vendor of doing something shady, when the problem is that the transaction isn't even in the blockchain.
It will be something that simple that will prevent bitcoin mass adoption.
Transactions that confirm definitely in a minute aren't a problem.
There were some places which accepted zero confirmation transactions for low value items, because they were sure that the transaction would confirm. This is no longer the case.
I will provide 1 second transactions that are confirmed on a block chain that can't be centralized by miners.
BitCON's 0-confirmation transactions depend on propagation, thus they can't scale without centralization
of control. And in fact they can't scale to 1000s of transactions per second and certainly not millions of txns/sec required for Internet microtransactions. Lightning Networks (LN) is proposed, but
it can't scale either and has other serious clusterfuck issues. Vcash's Zerotime also can't scale.
So sorry, BitCON can't scale without being centralized. But if it is centralized, then you
lost all the advantages of not being fiat and you've added the 666 enslavement.
Security and reliability cannot be copied.
(dont adopt segwit)
SegWit is the admission of the defeat of decentralization, BitCON will become fully centralized (which is what LN requires any way):
LN can't send a payment from Bitcoin address to any Bitcoin address. It requires users establish accounts in the LN before they can be eligible, i.e. it is an opt-in system and it is not persistent.
LN is an incredibly complex Rube Goldberg kludge patched on top of an inadequate block chain design and there IS a better solution coming. You have to discard the Bitcoin block chain and Satoshi's design and start over.
In general, Bitcoin is moving towards centralization over the control of which nodes validate and thus which can do capital controls and KYC enforcement on transactions:
