I've just bought a new monitor at Newegg.com, and paid with Bitcoin.

Payment went thru smooth and fast. Much better than using my local (Argentine) credit card, asking for authorization for a payment abroad, and informing my unfriendly gov about any usd movements.
The only drawback is that i spent my precious hodled satoshis.
Now a frenetic bullrun will surely begin.. This is going to be the more expensive monitor ever (0.07 BTC for the records).
Enjoy the +200 usd rise in minutes.. That was me, spending sats.
Crap, Newegg is taking Bitcoin again?
I still can't bear to throw out my $4,000 cell phone from a few years ago. Aarrgghh!!!
That's OK, I am still holding my "$325" iphone from late 2017...
...er, not really, but it shows that sometimes you can get a bargain if spending strategically.
Something to remember in 2021-2022 as we peak, hopefully.
The calculation should not be very difficult for any HODLer attempting to have some reflection regarding their own financial goals - and the extent to which they are trying to accumulate BTC or if they are trying to accumulate consumer goods.
Surely, there is nothing wrong with ensuring either a certain level of comfort or a certain level of practicallity and status with consumption of goods and services, but no member should be spending from his/her BTC without giving it some insight regarding whether spending cash might be more preferable or considering if spending from the BTC is taking profits or might be able to be replaced at a later date for equal or lower costs.
If any member is feeling regret about spending 10k in bitcoin for two pizzas, then that mistake had already been made based on non-appreciation of future BTC value, but if such member still has another 10k BTC that is in cold storage, s/he may not give two fucks that the $10k BTC happens to be currently worth close to $100 million..even though it was only worth 2 pizzas in mid 2010.
