It won't stop hackers... Just make what they do more dangerous. TBH the government likes crypto for one reason... The second you try to move it from your wallet to profit they will catch you. Basically the $5 mil they paid the hackers for the pipeline was already drained from the wallet they were put into by the FBI.
FBI been tracking crypto for at least the last 5 years. They have been catching people who have made money on the dark web with it. It's safe until someone needs to cash out... So it will be useless for hackers.
They should not have done this to the USA pipeline that has such a huge part of how a third of this country operates daily. They knew they messed up quickly and now the wallets they transferred the crypto to have been drained.
