Are these really safe since someone besides you has seen the private key? I have a Titan bitcoin from titanbtc.com and am wondering if I should redeem it. I can check the value but as the price of bitcoin continues to rise I find myself wondering if I should trust their security practices. I have no reason to doubt them as I've had the coin for years and it's stayed secure. So should I keep the private key coin or just try and figure out how to transfer it to my trezor?

Yeah, you should get this bitcoins and stored on your own device/software, I can't say that this platform will become scam since you said your Bitcoin stayed there for years but there still chances that this will happen since this platform is a kind of web wallet if I'm correct. So storing your own coins with full control of yours will be much safer. Hardware wallet or paper wallet is much better since you save your coins for long term.

Titans are valued by collectors. Why not leave it loaded and auction it off here in the Collectibles board?

Is it really safe? It's only really safe when you use a trusted provider, but physical storage devices are always risky so you think before using it.

Mostly they are safe. There's been only one physical cryptocoin provider that has had compromised keys that were stolen and then the affected coins were drained of their loaded value. It wasn't Titan.

If you want to feel better about it, stick with the known names - Casascius tops the list. I have several Casascius coins. There's so much value in these coins that if a coin creator committed fraud the whole system would be come devalued.

I think you might be misunderstanding the question. The OP is talking about physical bitcoins. People have minted coins and then loaded them with bitcoin, the private key is secured beneath a hologram that if tampered with shows damage very easy (it's a security measure.) The minter/creator of the coins at somepoint handles the private key so technically someone else knows the private key if you own one of these coins.

He's not talking about a hardware wallet. And physical storage devices aren't risky...but hey, you'll get paid for your post, right?

Not just Titans, but also other physical Bitcoins such as Casascius and Denarium. But as the OP has stated, no one knows whether these private keys are 100% confidential. There is a real chance that the employees of Casascius and Titan are aware about these coins and therefore it will be better to redeem them and store the coins in a hardware or online wallet.
