I was reading a news article saying that bitcoins will not be safe once we have powerful quantum computers. Is there a good alternative way to store bitcoins safely in such a situation ?

There are some solution to this already on the way.

However, if quantum computer can break bitcoin's security, it can also break banking security and etc.

By the time that happens, you'd also be concerned about other things that are put behind some form of encryption that now can be solved by quantum computers.

As far as I know , everything is still in the research and testing phase , there is no effective solution yet, but the threat from quantum is not so urgent so it will not be serious .

Banks and bitcoin both use the same algorithms like ECDSA and SHA-256 , which means that traditional systems will also be threatened by quantum computers. But the ridiculous thing is most of the news is only about the threat to bitcoin, no news about the threat of quantum computers to banks and their fate. It is clear that the quantum news was given for another purpose . Wink
