Doesn't seem like this bug places any risk on stored wallet funds, so it is unlikely to have much of an affect on the market. As the article says, the bug has already been fixed, cudos to the Bitcoin Core team for such a quick response.
the bug causes nodes to crash. a patch has been released /core client update released. but that does not mean that its solved.
people need to download the software. and run it
right now only 10% of the network is using 0.16.3
meaning over 80% of the network is still at risk
again 80% of the network is still at risk. this its not fixed. its just made available a tool that can fix it.
imagine it like an engine. engineers found the issues needs a special spanner to fix it. they made the spanner but now people need to use the spanner to fix it.
anyway the deeper issue is we need to decentralise the 'reference client' to stop being the center. there needs to be a change of mindset and to allow other teams to make their own clients that work onchain in consensus without being treated as attacking a king.
get rid of the kingdom and instead allow united states on the same level playing field. that way there would be diversity on the network and no 80-90% network dropping scenario
