You are misinformed. The smart contract which had a flaw in it is actually a shadowfork of the original PoWHCoin. People were greedy and immediatly jumped on the copycat without reading it through. 1 million dollars worth of ethereum is now stuck in this copycat. The original is going good and steady and has no flaws other than being a ponzi scheme :) You can see the original contract at this address: https://etherscan.io/address/0xa7ca36f7273d4d38fc2aec5a454c497f86728a7a. The broken copycat can be seen here: https://etherscan.io/address/0x9f4fd6c336388f2ab7dc7bbe4740ae7b88b880d7.
TL;DR: The original is still working and is fine, the copycat broke
