I also experienced what you experienced.
my transactions on etherscan already 1 day ago unfinished (pending)
its estimation time is not clear, because it increases every minute.
I have asked their marriage but they are only bialng to raise the cost of GAS. but I use 50GWEI.
But man ethereum has nothing to do with Bitcoin. Ether txs where congested because of a Chinese exchange Fcoin made a voting system to list through deposits. One deposit equaled to 1 vote so most of coins promoters where massively depositing to get their coin listed.
Regarding Bitcoin I don't really know what the issue could be. I did a Transaction yesterday and took me.like 20minutes to confirm.
