I checked all the private keys and about 24 addresses come back with transactions that occured over the years. Question I have Loyce is why would there be transactions on these addresses
You're asking the wrong question. You should ask why you have them on your computer, and you're the only one who can answer that.
if I supposedly the only one to have the private keys which don't seem to be the case?
Anyone can share, leak or lose private keys. It sounds like you've downloaded some of them.
Or do I not understand Bitcoin right? Would you like one of the addresses that has transactions?
Feel free to post them.
