Public vs Private Keys — or how not to lose your crypto like a rookie

So here’s the deal — if you’re new(ish) to crypto and still figuring out how keys work, read this before you learn the hard way.

🪪 Public key = your “hey, send me crypto” address.
🔐 Private key = your “this unlocks everything” secret. Lose it? Game over. Share it? Also game over.

Yeah, it’s that simple. And that brutal.

There’s also the whole custodial vs self-custody thing.
You either:

A) Let a platform handle your private key for you — easy, but you’re trusting them with your money.
B) Hold the key yourself — ultimate freedom, ultimate responsibility.

If you’re going the self-custody route, for the love of Satoshi — back up your key. Offline. More than once.

And yeah, if you’re using a wallet that lets you choose between self-custody and custodial options — make sure it actually respects that choice.

That’s what we focus on at Quppy.
No forced one-way storage, no hidden access — just a clean setup where your keys = your rules (if you want them to be).

Because at the end of the day, crypto’s about control.
And we think users deserve all of it.
