No. Bitcoin is the future of money. It really is the best form of money humanity has invented so far. People just need to stop trading shit coins.
Bitcoin (as it uses proof of work) is incapable of handling all transaction of the world without creating insane amounts of wasted energy.
Updating the ledger (actually writing down transactions) is only a fraction of the total computing resources it consumes. Most of it is just spent doing random hashes over and over again (the proof of work part). This is computing power that does not actually do any of the money related tasks, it's just there to keep the ledger trusted.
This is an awesome idea in theory, but completely unscalable in reality.
Other Blockchain technologies like proof of stake don't have this issue of energy waste, but they have other hurdles.
But Bitcoin as it is implemented now can never be the money of the future in my opinion.
Trust is one of the most fundamental parts of any monetary system, so brute forcing hashes in this case is directly related to it.
Bitcoin can easily serve the world on 100 Mac Minis. Probably even fewer. The fact that currently people beat themselves into burning ridiculous amounts of electricity to run Bitcoin nodes is a function of the profitability of doing that. If that profitability decreases, so will the electricity burned. If I remember correctly, the protocol is designed to reduce that reward over time and unless the dollar value of Bitcoin dramatically increases, the energy waste should decrease long term.
A secondary point on energy consumption is how that of Bitcoin compares to the traditional financial transaction systems. I don't have the numbers at the moment but last time I checked it wasn't pretty for the latter.
With all that said, if PoS is proven to be as robust as PoW, it would probably be adopted by systems currently on PoW, like Bitcoin.
I think you're missing a critical part of how blockchains function: If Bitcoin was running on only 100 Mac Minis, there is nothing stopping someone buying 101 more Mac Minis, becoming dominant in the network and suddenly they can decide to just print their own bitcoins for themself.
The profitability of running Bitcoin miners is proportional to the market cap and the value of Bitcoin itself. For Bitcoin to remain stable, the total value must remain less than the cost of hardware to dominate the consensus algorithm.
Can you elaborate on how one could print bitcoins if they controlled 50% of the network?
Bitcoin miners validate transactions on the network, so if one entity controls a majority of all miners, they can validate their own fraudulent transactions
I don't know if you've heard about Lightning Network, but this is a layer on top of the bitcoin blockchain that is much more suitable for small payments. That's how I do most of my bitcoin payments now, and while it's still a maturing technology, it mostly works well. Transactions are fast and inexpensive.
Yep, first is always best, like my CRT TV.
Ethereum is pretty cool too. I'm not a Bitcoin maximalist. That's pretty much it though. the rest are shitcoins. Edit: Monero is the other good coin.
Do you use Bitcoin in real life?
Do you use any gold in real life to pay for stuff?
No, and I also seriously question people's obsession with gold.
No, just virtually.

it's_a_jokeI used to work at a liquor store and we had one regular customer who paid with a bitcoin card. This was around 2015 or so. It was funny because he said it was because of "anonymity" but everyone knew him as "the guy who pays with bitcoin."
bitcoin will never be the dominant global currency. it couldn't even maintain its position as the dominant darknet currency. bitcoin is not perfect and you are part of a religious cult that bans people for pointing out its shortcomings.
No fucking way haha, imagine having to hang out at the grocery store for an hour waiting for your payment to clear
Yeah man, keep huffing that copium.
Bitcoin has no long term plan for actually securing its chain. The fees don't add up to enough and the throughput is abysmal. Lightning is centralised and was disrupted because of chain congestion due to Ordinals.
Keep dreaming!
