I was a first-mover on all the top 3 marketplaces for every product I listed. Many copycats now, but the market is big enough for us all to eat.
Every printer has an hourly rate. Think of it as "the value added per hour of unassisted runtime".
If you have a valuable use for the machine, it doesn't matter how much you paid. Its not that hard with good credit to get a $2000 loan.
Anytime I'm about to buy some piece of plastic, I do a quick search to see if I can just print an alternative instead.
No need to learn modeling. You just need to learn how to slice other people's models.
perhaps i could also sell 3d files...
Information wants to be free. Selling bits is really, really hard.
I've printed hundreds of parts for my own use around the home, office, shop, and computer lab.
Organizers, display stands, cute plant pots, cases for SeedSigners, novelty toys for kiddos, really the only limit is your imagination.
Don't cheap out on the printer unless you like to tinker! Bambu Lab makes the best printers at the moment, excellent performance, hassle free.
I paid $1500 for my printer 2.5 years ago and now it pays for itself every 3 months just by selling printed parts online. Even tho my printer has outperformed BTC, it is not risk-free and there is some work to create the ecomm listings and pack and ship every item, dealing with customers, etc.
Catch is it's a .TOP domain, but the registrar is legit: https://www.trustpilot.com/review/porkbun.com
Enterprise (professional/enthusiast/uncle jim) nodes tend to run in a virtual machine environment (and/or in the cloud) where increasing storage size is as easy as updating a config or the storage automatically expands.
Additionally, people use their nodes with different "loadouts". Some may also have electrum or fulcrum index running alongside (adds 100-300GB). Some might be running mempool project locally (add some GBs). Some may be running other nodes like a Monero node on the same disk (adds about 300GB). It means not "everyone" will run out of space at the same time.
Sometimes miners can maximize revenue by (counterintuitively) including lower-fee txns.
Maybe those txns paid a fee "out of band" (like Mempool.space Accelerator). Or maybe those txns were involved in some MEV (Miner Extractable Value) scheme.
Additionally, not all miners' mempools are the same. Some mining pools run alternative BTC node implementations like Libre Bitcoin or Bitcoin Knots which have different mempool policies and therefore a miner may exclude a high paying tx that isn't in their mempool.
I thought the US wasn't selling its BTC?
Crazy how "big news" manages to stay out of the bitcoiner zeitgeist when its not bullish enough. Narrative vs reality.
The LN would split based on which nodes were on which side
Its also likely that many LN nodes would support both sides of the fork. At least at first...
Whats stopping you?
All the new ASIC models are three-phase (380V) which isn't even available in most residential circuits.
Surely there's something Zeus could add to expose the channels.db from within the app so people don't need to dig thru their phone's filesystem in the first place.
Also curious HOW op initiated the RBF. Does zeus let users footgun themselves like this? Or did op rbf from another wallet?
This is why many places of business require 3-6 block confirmations to render goods/services. However, as miners get more centralized, this should really be raised to 10-30 block confirmations, if you don't trust the miners to play nice.
For a malicious miner to cause a deep reorg,
they would have to first "withhold" those blocks from the network.
Example:
Suppose Foundry was evil and wanted to reorg any chance they could get.
Suppose Foundry found a valid block at blockheight 900,000. Meaning, they found a nonce such that when combined with the previous block's hash (block 899,999) the resulting hash is below the difficulty target.
Instead of broadcasting block 900k, they hold it themselves and begin mining their next block on top of this withheld block 900k.
Now suppose some other (honest) miner found and broadcast their version of block 900k. All the nodes will accept this block. Suppose this block contained a tx of yours and you already received the goods/services you paid for.
Now suppose Foundry found block 900,001 but this block is only valid if you use Foundry's block 900k, not the block 900k that was accepted by the network.
Foundry can broadcast BOTH their withheld blocks and cause the original block 900k to be orphaned.
If your tx was "confirmed" in the honest block 900k, but does not exist in either of foundry's new blocks, then its like your tx never happened, but you still received the goods/services.
If any miner wants to be malicious and they have enough power (or get lucky) they could reorg blocks.
Here's a list of orphaned blocks: https://bitcoinchain.com/block_explorer/orphaned
If you think mining pools are too centralized, you should require more confirmations for your txns, when possible.
If you operate a LN node, you can set the min required blocks before a channel becomes active, for example.
If you operate an economic node (like a bank or business) you can require more confs before delivering the merchandise or crediting the customer's account.
Unfortunately, you cannot easily require more confirmations as a user requesting withdrawals from an exchange. Maybe your widthdrawl is included in a block that immediately gets reorged or orphaned. Your widthdrawl tx is no longer included in any block nor the mempools at this point. Your only recourse is to plea to the exchange and hope that they recognize the validity of the reorg and re-issue the widthdrawl tx in your favor.
Re-read page 6-8 of the white paper. Satoshi explains his reasoning and calculations.
In his examples, he estimated that IF the largest miner has 10% of hashrate, people should require 5-confs to reduce the probability that their transaction gets reorged to less than to 0.1%
A reorg happens when a miner is able to "undo" a block and replace it with multiple blocks which don't include your txn.
Foundry Pool regularly mines 6 blocks in a row. Foundry has approx 30% of hashrate today.
If Foundry wanted to be malicious, they clearly have enough hashrate to routinely reorg the chain.
So if we account for REALITY, satoshi would recommend requiring 24 block confirmations to reduce the probability of reorg to 0.1%.
If you start with high price then lower as you achieve scale, its a commodity product.
Or...
If you price low and raise as you achieve scale, its a luxury product.
If you compete on price, you're always competing with someone who has much lower costs than you. As a small biz, you gotta compete on something other than price to remain sustainable (be unique, be quality, be luxury)
The best luxury products can consistently raise their prices above CPI. This artificial scarcity can actually grow demand as fiat-minded consumers believe your garbage is a good investment.

Not necessarily. You're assuming that every watt of off-grid power is just a watt of grid power that would have otherwise been used.
Grid and off-grid are not perfect substitutes. Maybe they are close in Germany (I have no idea). But broadly speaking, not.
Industrial sites (bitcoin mines included) are often built near a power plant. They might even establish their own energy source that isn't grid connected.
solar is a useless energy source for society as a whole
Yeah, maybe if you live in Germany. But not if you live in near the equator.
Also, a lot of solar generation goes unmeasured because smaller installations are off-grid. Those figures shown for solar are likely only from larger-scale farms.
Energy consumption isn't the same as production. A lot of renewable (and nonrenewable) energy is produced that is never consumed, effectively stranded or wasted. One chart is confusing because its titled "consumption" but the chart axis measures "production".
Even the "obvious facts" don't include the whole story sometimes.
