I dont like that.
What i want to ask, can i spend a coin only having it in my hand without access to any list and so on.
Thanks in advance for helping me with knowledge
Not sure about key generation....I just use the address
And yes, you could "spend" a coin without a list. As long as you know/memorize the address and private key.
Easier to just "open" the coin and enter the letters and number.
All though, some makers use a QR-code, so unless you have robot eyes, you wouldn't be able to "read/scan" the code
And, some coins do come with the full address displayed ...depends on the maker/holograms/coin
Thanks
