Yes, the current $6.5M for 100 Bitcoins is a huge amount. This means that the op either didn't care much about his bitcoins or that the bitcoin value at the time he bought the bitcoins was so insignificant that he didn't think about its future. I believe op's story because op's account was registered on this forum in 2013. and until the end of 2017, the merit system was in the form of Airdrop, but at that time he was so lazy that he did not post that he used his account, so he is still in Member rank. so it is possible for him to lose the private key. It is a very sad incident
It is very rare for someone to accumulate that much bitcoin and then lose access to the assets they owned. My assumption is, if the story is true, maybe he bought bitcoin at a fairly low price, so he doesn't really care about the assets he owns. Even though he has been on this forum for a long time, it doesn't mean he has the opportunity to collect that much bitcoin. I've also been on this forum for a long time but I don't have as many assets as OP has.
Let's just say the story is true and I think the OP is quite a careless person because if he hadn't lost access to these assets, he would now be one of the new billionaires on the forum and in the real world. That is why it is important to keep a confidential key to the assets we own and this must be a consideration for anyone who must maintain the confidentiality of private keys.
