hai guys,
            in 2021 is the only transaction where there is an incoming of 2500 btc blockchain is most tursted since 2010 when bitcoin is officially launched and easy to store coins, instead of complex hardware wallets, i think there might be possibility that the guy wanted to use simple blockchain wallet instead of using complex hardware wallets, and the security of blockchain also very good.
             If he is a techie then he might be used wallets like armory, or some other strong methods to store his coins. i am thinking about the path option that i gave as some one suggested in this forum it might be any where with clinet_id like m/84/0/0 or m/84/0/1/0 i want to give a try without out the option bip-32-path in cmd for seedrecovery.
Thank you
