i created a wallet form web wallet
and an keeping safe 12 words and a bitcoin address public key and private key
and that single public address has all bitcoin now i m never going to use that wallet as i m going to hold bitcoin till 2025


my question is what if community tries to upgrade bitcoin and is it possible that that private key wont work because of upgrade.....as i see back in 2011 people use to keep bitcoins on a hard drive ....

i just want to know would i be able to recover my funds as long a i have my private key whatever happens to technology....
