I still don't get why would anyone hold their coins in a wallet that allows a finite attempts to log in.
Just keep your secret phrases and the fact you are playing around in the crypto field a secret.
Yes that's pretty stupid. I can think of so many things that could go wrong here like a kid gets a hold of it and starts spamming some stupid things and uses all your attempts or it gets stolen by a thief who simply locks you out trying to break it when he'd need weeks to crack it anyway using sophisticated software if you just used a strong password.
When you can remember a strong password or know how to hide it you can use a normal hardware wallet. If you prefer to use a short, weak password like "mybitcoins" you can use that ironkey thingy, but you'll always risk that if it gets stolen the thief can lock you out.
Also, why would anyone store 200 million dollars without a way to recover the wallet? You can forget password but what about the seed?
