About 4 years ago i gave my son some BTC for his Birthday....
Trying to teach him a bit of financial responsibility.....
he created a wallet, on an exchange i believe, i wasnt part of that, as i insisted he take charge and responsibilty for his own, and, keep passwords, seed etc safe.
Fast forward till now..... He can not remember which exchange he created the wallet on, i do have the original wallet numbers however...... dont have seed.
it there anyway to tell which exchange it went to , he " thought he saved all the info on his computer..... kids huh.
