Thankfully you don't seem to understand that article, or how this "leak" could work to de-anonymize Monero and the like, which isn't what was being talked about. Tracking transactions is not an issue, it is identifying you to be somehow related to certain transaction, or address for that matter.
Since we were actually talking Bitcoin, transactions are already in the clear. You may think in your mind Tor is useless, but you are wrong, but it is because you fail to understand the technology. Perhaps you are the type they target, please citizen obey the law, thank you.
Point of Tor is hiding your IP, and therefore your geo-location at a given time. This works and is not broken. Your alleged NSA tool fulfills another role, which is AFTER they have confirmed an identity to be tied with an address/transaction. This may* be needed in those coins, but not Bitcoin which is already in the clear.
As for your other article, i won't even bother. Chinese are not supposed to be dealing with Bitcoin, use your imagination...
*Hilariously most Monero wallets don't anonymize the transactions in the first place...In the end, if you know what you are doing, you are safe using Tor.
