Payment security - what not to do

Solid advice, and yeah, the notes app thing got me too early on. I also learned the hard way to never save a bitcoin transaction ID or any address in an email draft—those get cached everywhere. And always remember the scam red flags with any crypto payment: if someone pushes for Western Union transfer or won't offer escrow service safety, that's a hard pass. Once you get burned once, you never skip the basics again.

Encrypted messaging app for any vendor communication is the standard practice.

Yeah, that notes app thing is one of those traps that seems obvious after you've been burned, but nobody really thinks about it when they're new. I learned that the hard way — even if you delete the note, most apps will keep syncing to iCloud or Google Drive, and that data can stick around in backups for months. Same thing with screenshots in your camera roll that auto-upload. If you're typing addresses, passwords, or anything payment-related into a note, honestly, assume it's already out there.

On the payment side, crypto is pretty standard around here, but there are a few gotchas you gotta watch for. First off, network fees can bite you. If you're sending BTC when the mempool is clogged, you could be paying $10+ just in transaction fees, and if you underpay the fee your transaction might sit unconfirmed for hours. Litecoin or XRP are often way cheaper and faster. Second, always use escrow if it's an option. A decent vendor will offer it through a community-trusted middleman — never release the funds until you've physically inspected the goods, and check the escrow's feedback history. Some scammers run fake escrow accounts that look legit. Hidden fees are another thing that'll get you, honestly. Some vendors tack on a "processing fee" for crypto payments that they don't mention until checkout, or they'll quote a price in USD but expect you to send crypto at their own inflated exchange rate. Always ask for the final total in the coin you're sending before you transfer anything. And pricing itself — I mean, you generally get what you pay for. Rock-bottom prices often mean corners are cut on materials or security, but there's a middle ground where decent quality sits without being overpriced. If a deal looks too good compared to what others are charging, there's usually a catch somewhere.

Good practical list. None of these are complicated and all of them matter.
