In practice the primary use cases for Crypto Currency are:
1. Running scams (see: NFTs, most exchanges, etc...)
2. Speculation (HODL)
3. Laundering dirty money
4. Buying contraband (drugs, guns, etc...)
5. Tax evasion
6. Extortion payments (crypto-locking viruses, etc...)
7. 419 scam payments
8. There was once a way to pay for burritos from a specific restaurant using Bitcoin.
9. Everything else
It really shouldn't be a surprise that lawmakers have taken a dim view of the subject. That said, there are a handful of legitimate uses for cryptocurrency, but it's hard not to think that we could find better alternatives for those use cases, especially given the disastrous environmental impact of many of these crypto schemes.
For online purchases in my country Bitcoin works very nicely. Also for travel related purchases. I would estimate that maybe 60-70% of my purchases are in Bitcoin these days.
If I can't use Bitcoin at a store directly, I can simply take out some cash at a nearby Bitcoin ATM - nowadays there's more BTC ATMs than my bank's ATMs.
I very rarely use BTC in brick-n-mortar setups, in the last year once in a restaurant where I had a bigger bill and they had recently started accepting it - went actually very fluently.
It is not really that much different lifestyle to any normal life, I just pay with BTC where it works. And these days it works very fluently in online setups in my experience.
I just don't see how this is at all possible. Like, who are you paying bitcoin to for flights?
It feels like translating the real value of something (say $5) to something else (e.g., 0.01 BTC) with every purchase. It's just overhead at this point.
For most of your online purchases, you can go with a gift-card; though it's an annoyance compared to just having one single card with rewards and cashback.
There are hundreds of apps in DeFi, was 250B invested, over 10MM paid per day just in transaction fees, and 20k developers. The amount of users is growing as fast as the internet was during the 90s (we're equivalent to 1998 now) and almost every usage graph is up and to the right exponentially. Can see many of the metrics at https://defillama.com and https://link.medium.com/readqva7brb
Ethereum by the metrics looks like the greatest startup investment of all time. It was also the quickest to reach $500B market cap. But alas many are going to miss out because they miss the forest for the trees.
A16Z is definitely making the right moves based on the metrics. HN folk are blinded by emotions, and not bothering to do the research. The person you're responding to doesn't even know DeFi.
If you want to understand what DeFi is check my post history. I often talk about it yet every crypto thread is always the same dumb "only criminals use it" comments voted to the top.
Now, personally I don't have a lot of issues with the prevailing system, venmo and similar apps. I don't have any issues buying what I need online since credit cards work and are widely available.
I suppose crypto could be useful for industries that are legal, but banks do not like engaging with. Like adult entertainment.
Crypto adds nothing.
BTC is expensive to transfer, but other options like LTC are not. It takes a small fraction of a penny (in USD value).
Anybody who has tried to pay for something directly with Bitcoin will see the problem instantly. The mining fee is a significant percentage of your transfer unless you're sending literally thousands of dollars worth of Bitcoin and it typically takes 4-24 hours for the transaction to clear unless you're willing to increase the transaction fee significantly.
Crypto currencies are so bad at this that PayPal is a better way to transfer money. Let that sink in.
Not that I have much problems with any payment methods. I just prefer to hold Bitcoin and use it as my primary currency. I'm willing to willing to spend some extra effort to pay with it, but if it gets too difficult I'll resort to fiat.
To me it's the same thing. "Law resistance" is a prerequisite for censorship resistance, because governments are often the ones doing the censoring.
I think there is no need mixing the two. Use normal banking, companies and taxable jurisdictions for white money - everyone needs some white income to explain what they are doing - and crypto for the rest.
Crypto people i know (the real ones), want it illegal, because then their work has fewest impediments - it becomes nothing but coding in R, Solidity, some Python, and occasional visits to a guy next block for a pack of cash. No paperwork.
