Hi all, I sent a fraction of a bitcoin through my ledger nano s and found 8 other sending addresses confirming at the same time.  When I checked these addresses on blockchain transaction viewer, I noticed that the main node was for 17BTC. I don't have even close to this amount of BTC, yet all of the 8 transactions - including mine were all originating from this 17BTC node. I also noticed that they were getting confirmed ahead of my meager 0.06BTC transaction, slowing my confirmations significantly.

Has anyone heard of, seen or experienced anything like this before?

-Thanks
BTC
