I already have bitcoind running with a 4GB pruned database, and I'm hoping that will be enough.
It is! By running bitcoin-core, you can pull this data in an easy, trustless way.
I would recommend creating and displaying a new address to your patrons each time a new donation is received (so as to avoid address reuse, which is detrimental to your privacy, and ...

No, you need the password to spend any money in the wallet.
The keys are encrypted with the password you provided.

"Buy the dip" is used by traders even for legacy markets and nothing specific for Bitcoin.
This will undoubtedly incur high network fees
For paying less in fees while moving bitcoin from/to exchange do the following:
Use P2P exchanges: Bisq and HodlHodl
Use open source bitcoin wallets with active development and support for segwit
Use RBF for ...

Your keys are stored securely on the hardware device itself.
If Ledger (or Trezor) goes out of business then their wallet client will also most likely not be supported anymore.
This isn’t that much of an issue. Other wallets have support for interacting with your hardware wallet, like Electrum for BTC, Electron Cash for BCH, and MyEtherWallet’s website for ...

All wallet software that I know of has migrated from JBOK to some form of deterministically derived keys. The first wallet with deterministic key derivation that I know was Armory around 2011-2012, and its scheme inspired BIP32, which formed the basis of many key generation standards that followed. Obviously, software that predates these schemes did use JBOK ...

According to https://en.bitcoin.it/wiki/Private_key
any 256-bit number from 0x1 to 0xFFFF FFFF FFFF FFFF FFFF FFFF FFFF FFFE BAAE DCE6 AF48 A03B BFD2 5E8C D036 4140 is a valid private key.
So if someone generates a private key using the usual random process, and then you generate a private key using a random process there is one chance in 0xFFFF FFFF FFFF ...

if the hardware wallet company ledger goes out of business, what will happen to my crypto asset / private keys in ledger?
It's difficult to answer about other cryptocurrencies and security of each. This website is for Bitcoin and you should be fine even if hardware wallet company like ledger goes out of business because they don't have access to your ...

This is what safe deposit boxes are for. Write your passphrase on a piece of paper and put it in a safe deposit box at a bank that will allow only you (with proper identification) to access the safe deposit box, until you die, whereupon access will be available to whoever you've designated through proper legal documents.
If you are worried that some bank ...

Cloud mining services are scams generally
Are there any legitimate cloud mining services?
Is a cloud mining subscription worth it?

If it was between 2010-2011, it must have been MtGox [dead], Britcoin [dead], Bitmarket [dead], Bitstamp [alive], Kraken [alive]. If she's lucky, she used Bitstamp or Kraken.
She stored the BTC on the exchange or did she ever transfer any to a wallet?
If you know the company or individual who owns the domain her email was registered on, I'm sure they'd be ...

Developers of reputable wallets use a suitable source of randomness and will generate a key in the whole range available, not restricted to some arbitrary small range.
So far as I know there is no standard (e.g. BIP) that specifies this. It is assumed knowledge.
For example see https://www.freecodecamp.org/news/how-to-generate-your-very-own-bitcoin-private-...

I have seen people say that you just need the private key and "some software" to recover your bitcoin. What does this actually mean in the real world? Can someone give an example?
What it means is that your funds are secured cryptographically, and not on a server somewhere.
If you lose your private key(s) there's no customer service rep that can ...

If the computer that stores the bitcoin is destroyed, how does someone access their bitcoin?
Buy a new computer, download and install almost any wallet program, then either restore a backup of their wallet data file or key in their secret number or key in a phrase of typically 12 or 24 words that is turned into their secret number.
I have seen people say ...

When Alice pays Bob, she creates a Bitcoin transaction. Her payment to Bob is defined in an output of the transaction. This output is encumbered with a cryptographic challenge tied to Bob's public key. You can think of this as the funds getting stored in a lockbox addressed to Bob. When Alice's transaction gets confirmed, it gets recorded in the Bitcoin ...

Is it possible to do this in PHP?
So far as Bitcoin is concerned, I believe it is probably possible.
For example, by looking at https://en.bitcoin.it/wiki/PHP_developer_intro I can see
The easiest way to get started is to run Bitcoin in daemon mode with which PHP communicates via local HTTP requests. A library called JSON-RPC is used to call the various ...

it says spent and what does that mean
It typically means money was received in one transaction and later spent in a second, separate transaction. It is a historical record. You no longer have that money.
It did not arrive to the wallet i sent it too!
It may be due to one of ...
The transaction fee was too low and you need to be patient.
