Is crypto era over?

If blockchain is to ever replace FIAT money, it would need to be regulated and recognised as legal tender.

Otherwise you could go into a shop and be refused service because the coin in your crypto wallet isn't accepted by the retailer.

Nobody wants to be dealing with that

And if the crypto coin became ubiquitous and so was accepted everywhere, without regulation, you're putting basically all of the liquid wealth in the entire country into the control of a private group and private exchanges that, as we've seen over and over and over and over again, will steal all your money

Plus, all the middlemen, creating apps and services so that the ordinary pensioner on the street can access their wallets opens up risks of scammers and malware and ransomware taking people's life savings....

The problem crypto solves as I see it is more transparency/immutability on a ledger. Companies at present do business and they've got accountants on both sides with different balance sheets and interpretations. There's a lot of money flying around in the system that isn't taxed. That's right from the people at the top of companies down to the person on the till who's trying to find a way to pocket money by voiding transactions or whatever the current flavour of the month fraud is.

The CEX's seem to be ran by cowboys at the moment but once regulated entities backed by governments enter the fray you could expect less fuckery. You'd always have the option of self custody (for some portion) of your money as well. Again governments could probably sieze funds that get hacked or stolen if they had some sort of ownership of the blockchain.

BTC will never be a good medium for payments it's for libertarian bunker residing hodlers. Ethereum for all its incredibly slow development seems to be making decent progress towards being sort of affordable for smaller transactions but I think Ethereum is more concerned with being a open ended platform for software experimentation rather than payments. Nobody wants to pay for stuff in volatile tokens anyway it'll be some sort of government backed stablecoin that becomes the standard for that. It just depends on whether the US Government decide the tech is good enough in 10 years, or at all, before they start dipping their toes in. It definitely feels quite a long way off being ready at the moment. Till then we'll probably see some weird and wonderful applications built, but mostly ponzis, cos ponzis are kind of fun.

Much like tech I don't think we'll see the financialisation of every bloody thing on the planet slow down any time soon because people inherently like trade, gambling and shiny new technological gimmickery too much.

Regarding security, couldn’t a big advance ins quantum computing end up superseding the block chain?

If that happens then your bank is compromised already and everything else.
