I feel like the real question here, or maybe it’s just mine and I’m misreading, is how do you safely buy btc to pay a source? I would like to know this specifically as I’ve never bought crypto and used this method before. Like the whole process simplified for a smooth brain ape if someone can please or pointing me to a good resource for crypto for dummies
1. Make three or more protonmail accounts.
2. Blockchain.com, create an account, don't put any private information(phone number sms, real name,), this is your external wallet that you will use for transactions that you will first send crypto to and then you pass it along to your source. You'll want to create a 12 word recovery/backup to recover your account in case you lose your password. You'll want to write or save your wallet ID. You will only use a wallet one time and then transfer that money to a new blockchain wallet and never touch the old wallet again, or transfer the crypto back to your exchange to convert it back to cash so you don't lose too much money other than fees charged by the exchange and blockchain.
3. You can either use a Kiosk to purchase crypto(like an atm). Or an exchange like Coinbase or Cashapp. Exchanges require private information. They can be linked to a bank account that allows crypto or you can use a debit card. Many banks don't allow crypto and that's why you have to call ahead to make sure yours does. There's lot of banks they won't allow you to link an account or use a debit card. This can force you to call around, but I also suggest you open a bank account that will only be used for crypto and nothing else so you don't get your financial info tangled up with your main bank. You just deposit some money into this bank and use it for all your crypto needs and nothing else, so if something should happen you close your account and walk away. When depositing cash into an exchange it's a good idea to just let it sit for a couple of weeks, this way the money clears and it doesn't throw up red flags(immediate purchases can get accounts frozen). Also by doing this it allows you after the 2 weeks to immediately purchase your crypto and transact with it right away, so you don't lose value on your crypto as the price goes down. You don't ever want to buy crypto and let it sit as it's bound to go down in value, just buy it and transfer it to your external blockchain wallet and then move it to your source that your buying from.
Crypto is a one and done process, you screw up and your money is gone. This is why when copying and pasting the wallet ID that is used for sending money and the address for receiving money you need to always check the first 5 digits and the last 5 digits to make sure it is correct before hitting send. It's also a good idea to take screen shots to back up your claim that you sent your source the money so you can cover yourself.
It's also a good idea to use a computer that has an easily wiped hard drive. You don't want to use a computer that you use all the time. It's preferable if you have an SSD, something like a chromebook that can be wiped in seconds.
This is just the basic outline of how this is done, there are questions that might come up when you're doing it that you can ask, but the main thing is to get your cash parked into an exchange, let it sit for a couple of weeks and then start the process of purchasing crypto, moving that crypto to your blockchain external wallet, moving that crypto to your source, moving your left over crypto back to your exchange to sell off for cash and letting this cash sit in the exchange for your next purchase.
Keep in mind that crypto doesn't hid your identity, it is simply a means by which to get money to a source rapidly without the source having to appear in person to retrieve money. This is done to keep the source somewhat safe, it's not done to keep you the customer safe, so you will leave a paper trail, but not one that would expose you to anything as long as your transaction amounts are kept small.......$500 or less. And the general rule is, never spend more than you're willing to lose as any source can close up shop and take off with your money.
