What is your story of not being able to access your Bitcoin wallet with Bitcoins in them.
What have you tried to retrieve them?
Maybe I'm just a lucky person that I didn't experienced losing my access to any Bitcoin I have until now.
Or because I have done a research first regarding the basics and that includes storing of Bitcoin before I invested on it and decide to hold some.
Retrieving them is easy if you remember the keys of your Bitcoin, aside from that it would be hard to retrieve.
