There can be several factors, maybe you sent a low commission and that's why it's taking so long,
The Main Factor is btc sucks, and using litecoin or dogecoin or any alt would have been there much faster.

This must be the reason why litecoin and dogecoin are worth so much less and have such a small trading volume. Because they're much better and BTC sucks. LOL
I have executed a transaction with BTC and I am now waiting for 6 hours and still have 0 confirmations.
Is the network jammed again for some reason? Or what is the deal with it?
It's not jammed. You need to pay 40 sat/byte. If you pay 10 or less you can expect big delays.
