| Bitcoin is a decentralized monetary system. Nobody controls it, nobody can print new bitcoins out of thin air, nobody can confiscate your bitcoins as they could from a bank account. The fees are quite low, considering that you can securely transact hundreds of millions of dollars of value for the cost of about $1. And I don't understand how does LN centralize the chain. Who gets more control and what exactly can they do with that control? Can they print more bitcoin? Can they seize funds? Can they censor your transactions? No. >Far from being a general-purpose asset, NFTs commonly have double-digit transaction fees to work with or mint, making them unsuitable for the vast majority of artists who are interested in them So they are beneficial only to a subset of artists, not all of them. I can live with that. upd: >There isn't really a version of this world where coins become tremendously valuable or renewable electricity becomes cheap and widely available, and we don't have any new miners entering the system. In fact, quite the opposite, the system relies on that not happening -- if electricity and GPUs get too cheap, the network has to scale or it becomes vulnerable to attacks from rich actors. This can be said about any industry that has to consume energy to create profit. All the actors compete for energy and try to outbid each other, eventually finding an equilibrium. The solution is to get more energy, so that there is enough both for mining and for videogames. |
It takes transactions temporarily off-chain making them more vulnerable to attack. Lightning Network is a system where the blockchain congestion is eased up by doing fewer things directly on the chain. It's also had a nontrivial number of privacy issues, some of them solvable but at least a few only solvable by expecting people to make lots of pools, which drives up transaction cost again, which kind of defeats the point. That decreased privacy guarantee feeds into fears about centralization and censorship.
The irony behind all of this is that systems like Lightning and even Bitcoin itself are kind of ripe for censorship. The blockchain maintains your entire transaction history immutably in public, and the only thing protecting you from having all of that leaked is if you use pseudonyms or mixers (again, increasing transaction fees and congestion) to transact on it. But then when you start reporting that stuff on taxes... it just becomes way easier than it should be to track people.
This is also something coming up a lot with NFTs, it turns out that censorship and centralization is about more than where your database gets stored, it's also about which exchanges will work with you and who will haul you into court.

Right, but I think the point is still that the rest of us aren't fine with y'all spending the equivalent of an entire worldwide entertainment industry's worth of power just to benefit an extremely tiny subset of the population, and that we see that as a very different outcome from decentralized finance.
You can bring up Bitcoin's benefits if you want, but it's not being used as a currency though by most people. It's not a financial system, it's a decentralized asset that people are speculating about. And maybe that is subjectively valuable to you, but it's not serving as a currency for most people, and maybe it's not good for a tiny subgroup to argue that their interests should be given equal resource budgets to activities that are accessible and useful to the majority of the world?
If the majority of the world was using Bitcoin, we might be having a different conversation, and we could potentially argue about whether the benefits of a decentralized financial system outweigh the downsides. But you don't have a dencentralized financial system, you have a set of assets that are being taxed as assets by the IRS, and that aren't really benefiting most of the world outside of some speculators.
