 I was fifth bitcoiner that visited this coffee place today, but first one to pay with bitcoin. 

We have more bitcoin merchants than Bitcoiners willing to spend. We don’t need more merchant adoption, but spenders adoption https://image.nostr.build/cbf45174577e3ce1928ea3b6ce009386788f80a12ca4e9ff71a2709442a98d25.jpg  
 We’ll get there in time. 
 YES. 
 Heck yeah boi 
 alby go makes me want to USE my sats even more 
 Seems economists were right all along 
 Save in Bitcoin. Use Monero. 
 Orange pilled a cafe today and paid with bitcoin. Slowly slowly butjust do your bit. Everyone does and it spreads. They have their first wallet and 2 customers paid in sats.  
 So true. People struggle to part with their sats due to the capital appreciation potential

 For short term cost horizons, the volatility of BTC is unknown, so fiat remains workable (or a stable coin) 

How do you calculate short term volatility & opportunity cost? 
 I don't.

It doesn't matter for a coffee. 
 For a one off coffee sure. It doesn’t matter at all 

But I am confused. Whilst I agree that owning literally anything else as well as Bitcoin, means to some degree you could be longer Bitcoin, a house, a car, gold, could all be sold for more btc

But to say the opportunity cost of using only bitcoin, instead of a less volatile asset (in purchasing power) short term eg eur, usd, aud, gbp, is exactly the same… how do you calc that?

From where I am sitting its not even possible to know what the opportunity cost is, given the unknown trajectory of Bitcoin, let alone say it’s the same 
 Spend and replace people 
 Each spend and replace is two records I have to track for taxes. I'm not doing that for a coffee. That's the problem for a lot of us. 
 Monero solves that.  
 I hope you report that zap then 
 I always pay these bills with NEW sats… never with the sats I hodl. @strike (and others) have a great UX to instantly take in your fiat and simultaneously send the merchant the value on Bitcoin/Lightning rails… 
 That’s a great dilemma. I mean, who wants to buy a $10,000 coffee! 
 What? 
 If you have fiat to spend in the first place you are short bitcoin.

Opportunity cost is identical.

There are no $10k coffees. 
 Yeah, true. 🥺 
 Buy me a spoon 
 It’s a hard uphill battle. I think what’s next is we have to figure out how to help people earn sats, so they have sats to spend 
 Many Bitcoiners want to hold their coins instead of spending them. Would you rather give up a valuable, deflationary asset or some of your government issue pretend money? 
 Truth !
Celebrating the flow of Sats is important.
Money has to flow like a river. 
 This make me crazy as well, in Bitcoin meetup people paying in Bitcoin are still very low and we have no capital gain tax, so nothing to report if you spend and buy back. 

Same speach, always, "why spend my BTC if it should worth more tomorrow?" Why I answer: "If you have the cash to pay, you have the cash to buy more Bitcoin, if you really believe it will be worth more tomorrow, buy at least as much as you spend, buy 1.2, 1.5, 2 times more of possible, when price is going down 2-3% or more, buy in advance for your next spend. Using your Bitcoin will only make it even more valuable in the long term."

On the other end, merchants who are serious about it should offer some discount, cards cost a lot, like 4-6% minimum, cash cost as well, you must maintain change, spend to keep the cash safe between 2 working days, insure the risk of thief... A merchant accepting Bitcoin without 5 to 10% discount is not serious about pushing Bitcoin usage. 
 People who have fiat to use have a shitcoin problem. 

How did that shitcoin get to their wallet and why isn't it btc already? 
 Or better Monero. Much more easy, when you do not need to track your buys and spends for capital gains taxes.  I use it everyday and merchants are understanding the "digital cash" use case. 
 We’re also convinced this is a key point. Bitcoin-preferred merchants will need to incentivize holders to part with the coins since without that all the benefits of using better money are on the merchant side. “Show me the incentives, I’ll show you the outcome” 
 There isn't any coffee worth spending BTC. 
 You may be pushing a rope. It may be technology and necessity have to fix this. Technology improving lowers the switching cost and necessity is something like frozen bank accounts or censored transactions. You might make individual progress here and there with education and discounts but Bitcoin is still a lot to take in, it’s still tricky to use, and fiat works “well enough” for many. 
 Defnitly. The biggest electronic vendor in Switzerland offered payments in Bitcoin 2019 and stoped it 2023 since there were not enough costumers paying with bitcoin to justify the inversions to keep up the payment method. 
 Spend and replace fixes it 
 Agreed but having easier non-KYC onramps to bitcoin would help this a lot. 
 one is not a Bitcoiner if one does not use it. 
sounds to me you’ve been the first bitcoiner there today. 
 Bitcoiners visiting bitcoin-accepting merchants and paying in fiat are larpers. 
 Agreed. But also what happens to my sats when I pay with them? Are they being recycled in the circular economy, hodled or immediately exchanged for fiat? 
 True but also depends on where you live. Here in Liguria Italy there's not many places that accept it  
 This is understandable. People want to  leave bad money and keep good money. If there is enough people (companies) accepting bad money, why should I spend good one. 
 What did you get? 
 Stack your sats 
Don’t stack your sats

What do I do lol 
 Can relate.  We have more businesses than the local spending supporters of bitcoin.  

If we want bitcoin ad a currency.  We need to use it that way now. 

Earn. Save. Spend. 
 I've been saying this since 2013, after I started the first bitcoin merchant directory. Even way back then I could scrape tens of thousands of businesses' info off the web that claimed to accept bitcoin, but I simply didn't have any shoppers visit that directory. Total ghost town.

It finally dawned on me that phase 1 of adoption (Store of Value) needs to be widespread before phase 2 (Method of Exchange) can begin in earnest. 
 I agree. The medium of exchange will take some time. As m2 and velocity of inflation continues, what is the incentive right now? I am confident this will change over the years. I like to use the weaker currency. If I earned in btc, I would spend btc
