so attacker can steal other currencies and then buy with them bitcoins...

Why so sure that other cryptos are very vulnerable to such attacks, once again, what kind of attacks?
The bad guy can do anything to steal cryptocurrencies, not always through online hacks, as there are some cases of "bitcoin rich" were kidnapped and demanded to be paid using bitcoin.

That's why, do not let others know that you posses so many bitcoins in your wallet, mix it with chipmixer Cheesy

and divide to some addresses.

how can this problem be solved?

This problem can't be solved, the evil will remain in this world until the end of the time.

I advise you to learn what is a 51% attack before posting non-sense, you clearly don't understand what people are talking about since you ask "what kind of attacks?"
Few cryptos have been victims from such attacks and it has been fixed since so I say YES the problem can be solved
