A lot of people posting that they successfully recover their funds for along time but how about those who have lost their Bitcoin? Is it possible in the future that there will be a technology that is specialized in recovering lost in just a matter of minutes or an hour? But on the other side Bitcoin holder are in trouble too as their funds might also be vulnerable and be compromise.
Please more answer to do this please.
Not sure what you mean that there are people successfully recover their funds, because we all know that once you lost your Bitcoin it's hard to recover. At least you found your lost private key or mnemonic phrase then you can get it back. But let's say there is one key phrase, it might be very hard even with a help of those supposedly individuals or companies and it could be scam after all. So just be careful though. For those long term holders, maybe they protected their bitcoin and knows how to practice security hygiene and keep their private key safe.
