Well, it has not happened to me yet but I benefitted from BNB coins. I had barely 5$ in it, and I forgot about it,the upsurge prompt me to check all my wallet and I was basking in profit.I had an idea recently, that I would check over past sites I've worked on to see if I ever received bitcoin in any way. I think it would be awesome to find a site that I used to frequent and see if I had any bitcoin. That would be a life saver for me. Have you ever thought to do something like that? Maybe you have bitcoin from an old job, not thinking it would be important, you never know. I'm going to go through all my emails to see just in case.
