vanitygen VS mempool

When you send bitcoin (from your hardware wallet), use custom fees and check mempool.space to prevent yourself from overpaying on fees. A standard 1 in 2 out transaction right now should cost about $0.40 usd

That's not really true. Wallet addresses are deterministic, assuming you're using valid open source wallet software, the addresses will be yours. The node your wallet queries depends on the software you're using, some like Electrum allowing you to choose any public server. None of these people have any incentive to lie about the contents of your wallet, but even if they did, you could check on a block explorer like mempool.space.

good idea.. mempool.space is my refer.. I think it's enough the 3 free values min,medium,max probably the chart on the other hand is a bit complex to interpret. Or do you know a simplified version of it?

Get a non-custodial wallet: This is where you start to believe you really have Bitcoin, but it is still not perfect. A non-custodial wallet (like BlueWallet) is one of the slow types of Bitcoin wallets (on-chain) but this is where I think you, as a inquisitive mind, should start. Others will start with lightning wallets so they can buy beer right away. BlueWalllet has you create a "wallet" and gives you "seed words" to write down and keep safe. This is private. Do not take pictures of it, screenshots of it, and do not save it to a digital file. Paper is really easy and there's no risk of undiscovered malware being able to see what you write on paper. You'll very quickly learn the lingo: "wallet", "addresses", "utxo", etc. When you receive funds, the wallet will show you your balance like Coinbase does, but it will also show you a "transaction id". This, you can use to check that your transaction is real by checking a blockchain explorer like "https://mempool.space" or "https://bitcoinexplorer.org/". You are now able to check multiple sources, increasing your belief that the Bitcoin is real.

I can pull the TX up on mempool.space, but it is parsed into a bunch of different fields (witness, sequence, etc.).

Unconfirmed low-fee transactions may get dropped from mempools over time. It is possible that the node your wallet is connected to has dropped it, but mempool.space has not.

Does mempool.space show historical stats like for example showing stats for a country like UK to show usually which day and gmt time of the week where the mempool is usually at its lowest? I ask because observing the mempool space on screen 24/7 to time the cheapest fee is not feasible lets say lol.

tx.street is the mempool.space equivalent to bitcoin segwit transactions only and mempool.space is for legacy bitcoin transactions?
