So basically using multi-Sig cold wallet on airgapped machine provides the ultimate security?
I was thinking what if someone generate the same private key as my address in case of single address (which is very very unlikely) but using multi-sig makes this impossible,yes?
The chance of you messing up the multisig, and losing access to your funds, is much larger than the chance of someone finding your cold wallet's private key. The latter is just not going to happen (unless you make a mistake), the former can easily happen.I was thinking what if someone generate the same private key as my address in case of single address (which is very very unlikely) but using multi-sig makes this impossible,yes?
From your topics, you seem to have a hard time understanding how secure Bitcoin is. Maybe you should spend some time trying to brute-force the private key to a funded address, to convince yourself it's not going to happen.
Now i am not having a hard time understanding how secure bitcoin is But it wouldn't hurt to know more about cryptography in general. Does it? and it's a technical sub forum.
Also like you ask there's no harm if public key in known. So why to hide it? I know this BUT it wouldn't hurt to conceal it for privacy reasons does it?
See if the bitcoin devs didn't care about it they wouldn't introduce Taproot which essentially enables multi-sig wallet to conceal their pub keys and aggregate them into 1 key and no one can find out the real pub keys which is great IMO and helps in privacy. Even no one can find out if it's the multi-sig tx or single sig
