is there any chances of getting your Bitcoin or ETH wallet compromised when newbies generates new address?
I don't know much about bitcoin - but I'll take an example on the ERC-20/BEP-20 wallet (private key)
Example:
Keystore File
Mnemonic Phrase
private key
Access Wallet with Private Key: each digit number will produce a different seed even though there is a similarity of 1/2 digit number:
WALLET ADDRESS
0x4c93Cfb5B1b0Dc7F8404B16FBE3AA0202D2DA208
PRIVATE KEY
0xfed250ea887a9a75a1dee7a1bdf9414544ffc5a4a72029ac6511b63cc00f224e
MethodID:
0xfed25[01]: 123450ea887a9a75a1dee7a1bdf9414544ffc5a4a72029ac6511b63cc00f224e

It is possible that a bitcoin wallet can generate a wallet that's been in use by another user?
it is possible and you can find out based on the wallet address you generate whether it has been used by other users before or not. (transaction history)
I could be wrong, this is just an example based on my knowledge.
