Recently many people who bought bitcoin years ago find themselves sitting on an untouchable bounty. Those lucky guys who purchased or mined just a few bitcoins at the start of the age of cryptocurrency nowadays can boast about their savings. However, some of them are now in a painful limbo，because they can't remember the complex security passwords needed to get to their bitcoin wallet. Unlike a bank, bitcoin has no central hotline to call for a reset. This is really a bad thing，it's like forgetting a bank account password, but there's no bank to call to reset it. That money is lost forever. That might be a lot of money at todays exchange rate.
Actyally, this bad thing happened to me last year, and my friend recommend this website：
http://recovermybtc.com/ to me，she said she has retrieved her bitcoin wallet password through it，and I download this software，it really works after I used it，and you need to pay some service fee to them, but it's not high.Somebody who lost their bitcoin password can make a try, good luck.
Forgetting password is a very big problem because if we forget, we might lose all that we have in our wallet. It might be very difficult for us to recover it without the risks of someone stealing our money. So I think all of us must be very careful and should be responsible enough to keep our passwords safe.
