Original Matrix is one of the best movies I ever watched, but they ruined everything with every sequel movie, that was done just to make more money.
I wouldn't say that matrix that was described in movie is a real thing, but this world is not what people think it is, and what they are telling us since we were kids.
I know that if news and some big government agency is telling us about something, real truth must be a total opposite from that.

I have searched if there are any threads here about Rabby Wallet and it seems there are none. I was using a metamask for my daily use. But for me, the meta mask works too slowly. Recently, I found out about Rabby wallet which works exactly like a meta mask but faster, and it has some extra features as well.

Rabby is much better wallet for ethereum and all other evm chains than metamask.
I like that you can install Rabby on desktop (not possible with metamask), use it as browser extension or download app for mobile devices.
Another advantage for Rabby I found is better support for different hardware wallets.

Maybe an alternative method here would be allowing users to also sign messages with ethereum, as this an altcoin forum.

Is someone actually using signing and verifying messages on other blockchains?
I never heard about that and I never saw this was possible in all altcoin wallets I used.
I suppose this would be possible with bitcoin forks like Litecoin, BCH and others, but I am not sure about ethereum.

However, many people use USDT on TRON, and many services accept payments in USDT on TRON.

That is correct, but I can easily swap between chains and send with Aqua wallet I can pay directly from L-USDT to Tron USDT address.

Well, all crypto is kind of complicated for the average user, which is why average users mostly use PayPal. I think if some people pay with USDT on TRON, they have already figured out at least something about crypto, so they can probably figure out how to buy energy too. But if you or anyone have any ideas on how to make the purchase process simpler and more understandable, we would be happy to hear any suggestions.

There is no energy, bandwith and other stuff on other blockchain, that is making everything more complicated on tron blockchain.
I can't easily know how much I need to pay for transaction on tron, like I can find on bitcoin, ethereum and other chains.
Maybe there is some tool for that but I don't know about it.

Some time ago PayPal created their own version of stablecoin PYUSD that has the value of $1 USD and it is backed by dollar deposits, US treasuries, and cash equivalents.
Until recently PYUSD was a token on ethereum blockchain, but now they added support for solana blockchain with confidentiality transfers, and that part was interesting to me.
Sender, receiver and government regulators will be able to see this transactions, but for everyone else they will be not be visible.
For the record, I don't trust solana at all, they had multiple downtime flaws, bugs and it is centralized blockchain.
You can read more about that on Solana blog post:

Linux is better with pretty much every computer except for the ones that have shiny new firmware for which there are no open-source Linux drivers for it, yet.

There can be some issues with brand new laptops and drivers for new components, but this usually gets reported and updated quickly for major linux distros.
On the other side you can expect to have constant bugs and problems on wind0ws, you need to pay to use it and they will 100% spy everything you do.

In comparison to Tron, USDT on Liquid does not look like a success at all.

Tron on Liquid looks much better to me with cheaper fees and confidential transactions, but Tether is Tether on all blockchains and networks.
Most of the volume on Tron chain is artificial and fake, and you can't really compare it with something that is build on bitcoin with only few available tokens.

I just heard confirmed news update that Roger Ver was released on bail, this happened few days ago so it's possible that he accessed his own bitcointalk account.
I don't know how much money he had to pay for this temporary release, but it's probably a lot.

How is anybody supposed to stay sane in there? They should copy the Nordic countries' prison model (Sweden, Finland, Norway and so on).

Finland have the best conditions and their prison is more like a hotel with separate rooms.
I don't think Spanish prisons are like that but they are probably better than most prisons in United States.
