Just flagging the post above as a fake news article.

The article doesn't even mention which exchanges were affected. FYI, you can always check Ethereum network congestion using https://ethgasstation.info/ and currently as of writing ETH gas price is only 1 GWEI. Thats like $0.01 for a high speed transaction.

TLDR: The article shills some other shitcoin by spreading fake news. Obvious malicious intent.
