1 USD is worth 1 USD because you can pay 1 USD of taxes. It is backed by political promises, oil, weapons and war. This can’t end well.
Crypto means cryptography. Cryptocurrencies are a variety of things from stablecoin (digital token backed by fiat money often by a private company ), company shares, community projects, scams, scams, ponzi, scams, cool technical experiments and technically bad experiment. In the other hand there is Bitcoin (and Monero to some extent) that is owned by humanity, no foundation, no company, no state. It is backed by a proof of past energy brining the most innovative security system in the history of IT, not based on restricted access and opacity but by economical incentive to play fair with others in a big game theory peer-to-peer network.
Bitcoin is not the money of the internet. It’s the internet of money.

To keep it short there is two big families of wallets. Hot and cold wallet. Hot wallets are the one that got an internet connection wether it’s a constant one or periodically connecting. Cold wallets are never connected to the internet and often are dedicated hardware devices with the better ones having a Secure Element to store the private key or even sometimes sign transactions directly in it.
Victims of this attacks were using hot wallet on a not-dedicated machine which is consider bad practice. Hot wallets have to be consider more like a physical wallets for daily spends and cold wallet being privilege for long-term saving and monthly or yearly transactions.
I’m not an expert but desktop OS (especially Windows) are not as well contained than phone so I almost never use hot wallet on my computer. Often users are tricked to sign transactions to get stolen but I think if the wallet is unlocked a malware with the right privileges/permissions could easily steals money.
by reading some file in the computer Aren’t Steam games always executable for Windows?
Modded Wii is indeed awesome, I recommend you to check how to improve graphics on modern pannel if you don’t have a CRT TV.
OG Switch modding is great but offline only if you want to be careful.
3DS is indeed awesome for homebrew, I know PS Vita (especially the OLED one) are really appreciated.
PS2 is another great system to mod and with of course the gamecube!
These are PC games (either co-op adventure or party games) than can be played locally and that I have enjoyed myself (in no particular order). Bold ones are my fav.

So there is a network and backbone to it.
Yes, Bitcoin is not a currency, it’s an open permissionless network of trust secured not by access right managment and opacity but game theory and past energy. Very useful to build currencies. I recommend you Andreas Antonopoulos work, his content age very well and everything is under CreativeCommons. A great video to start is : What is Bitcoin and why does it matters?
The problem with current transactions isn’t the money itself, it’s the services that use that currency.
It really depend where you live. For Venezualian, Lebanese, Turkish and many more people there is huge problem with their currencies and banking services. Also in Africa many ex-french colonies are forced to use Franc CFA which is basically an economic-leash by the french government. We can debate on the many issues with the USD currency but these are little (for now at least) compared to others.

As far as I know both of them are also payment processor, not only currencies.
Why would I use a third-party to store or process my Bitcoin payment? That’s the whole point you’re not forced to use a trusted third-party to store or pay. I don’t, never did.
As a swiss citizen I can tell you that there is way enough regulation covering that currency, in fact it is regulated as foreign currency (currency of cyberspace hehe). I don’t know how it is outside but also looks heavily regulated in EU and probably is in America.
I know, I’m not that stupid :D It was for the meme cuz this is the internet.
The main issue is that regular payment processors don’t do what they are suppose to do (process payment and nothing else), they freeze account for no reasons (GrapheneOS, flipper-zero, etc…) censor payment because they don’t like an industry (closed an entire plateform (UTip) because of one adult content creator), industries that already are regulated by law. Holding users funds longer than needed, or censoring for political opinion etc.
In this regard Bitcoin is neutral : You have the money, it’s a valid transaction. You pay enough fees your transaction will be confirmed sooner. Who you are, how you get this money and why you are sending it is none of the payment processor business.
I have made this apps recommandation list that has a launcher section with what I consider being the bests

The problem is copyright that benefits only a tiny group of giant companies known as “les ayants-droits” in french. Copyrights as of today are not made to benefits the artisans, the workers but the black-suit men. The whole culture has been walled like that… The music industry, cinema industry and now game-industry…
