I've made lifechanging money with bitcoin. But because I just save it, my life is still pretty hard (parenthood stress, property stress, health problems etc). Anyone else feel emptiness as their net worth rises?

I have no temptation to spend it. I just wish other aspects of my life were as easy to fix as "buying bitcoin". Anyone relate?

Edit: you guys are awesome.

I have $200 that I want to invest and zero actual experience with crypto. Should I spend it all on Bitcoin?

How are digital signatures secure?

Hey everybody, I’m currently trying to learn about digital signatures for my essay on how cryptocurrency transactions work but I’m lost. I understand what a digital signature is but I don’t understand how it’s secure. I mean this: Let’s say I want to send my document to my friend James. What videos have been saying is I run the message through a hashing algorithm. This produces a digest which I use twice once to encrypt using my private key forming the digital signature and another time encrypting it with his public key so only he can access it. I send them both off together. So ok. I get how he verifies it comes from me by comparing if the digests are the same, but doesn’t that risk how the information is safe , as if a miner wants to validate it comes from me he can use my digital signature to decrypt the message and then run it through the same hashing algorithm that Bitcoin uses and gets access? Essentially, are Bitcoin transactions confidential or not, as if they’re confidential wouldn’t using a digital signature if decrypted show you how much was transacted between two wallets?

Does Bitcoin use authenticated encryption?

Authenticated encryption is when you sign a message with your private key forming a digital signature, then add that and the message together and encrypt it using the person your sending to’s public key so only they can access it.

Does Bitcoin use this? Or only send off the transaction with the digital signature?

What dictates a transaction as valid ?

Hey everyone I’m having trouble understanding what makes miners reject a transaction or what they examine to ensure a transaction is valid as well as what the network does to do that as well. Someone please help explain this. Thanks

How are Bitcoin miners incentivized not to validate false transactions ? And how does the validation actually work?

Hey everyone, I understand what proof of work and the mining thing is is and what proof of stake is but I can’t understand how they validate transactions , what do they do? I know what digital signatures are just to save you explaining it. It’s just the validation I don’t get.

so with proof of stake, validates are incentivized by inputting a security deposit higher than that of the transaction they’re validating, so if it is false and they get caught, they lose their money. Can someone explain how they get caught?

Also with proof of work, what’s stopping a miner from simply validating a false transaction? They are still adding the transaction to the block, like how does it get flagged in the first place?
