Teach people to follow recommended security practices when handling cryptocurrency + educate them on the technical basics + create pressure on 3rd party services to implement most secure solutions (i.e. multisig wallets).

If you want hackers to disappear, you need to take the opportunities away from them, meaning legit users need to do their homework.

there is a lot of unethical hackers that they do what they want to get money we cant do anything about that

It is impossible to curb hackers. But who forces you to keep cryptocurrencies on the exchange? After the auction, take them to a cold store and there will be a very small probability that you will be robbed. It seems to me that the security of your funds is your problem and those who neglect security pay for it with their money.

Crypto currency is working on hackers so that the coins get safe. This would be really great. The investors will get more motivation.

the "cryptoworld" is not prone to hacking. people are. and they have always been as soon as computers and the internet were invented and they started using them without educating themselves first. it is a bunch of simple security measures that if you follow you will be safe from all of the hacks and malicious attempts to rob you.
and it is not the reason for lack of investors. at least not the main reason. the main reason is all the FUD that is around in the media against bitcoin. when the public is bombarded with negative statements from famous people like Warren Buffet, Jaime Dimon,... constantly talking about bitcoin and attacking it, they won't feel safe naturally to buy bitcoin.

The blockchain technology cannot be hacked and it's a decentralized system that's why it is very hard. Bitcoin too is hack proof. Major hacks have been happening in cryptocurrency because many people that don't study the technology went careless with their innovations. The hacks happen through third party websites. So it's best for people to understand how to protect themselves and avoid exposing their private keys to any how.

I think not, all that is valuable to people is sure to be stolen even though it's not related to computers and technology.

Sad to say but yeah it is true, it's just there are some people doing illegal stuff here in cryptoworld not just hacking, there are many kinds of evil doings here like scams, using Bitcoin to buy some drugs and othersstuff like that. But hacking is the most popular one. Like me earlier i have visited again another myetherwallet phishing site, luckily i did not give any private key cause i felt there is something wrong about that site and yes i am right, my friend confirmed to me that it was a phishing site. Lesson learned again  , and the best way to counter those hackers is to become vigilant.

Yes but there are many reasons why their crypto getting hack and one of it is the frequent accessing on their digital wallet where hackers could phished out their private key and wallet address. Aside from that there are fraudsters also claiming to be an admin or marketing officer offering good things in return to submit a form which ask for private key and they already phished out by the hackers.
