Many people fall victim to a hack and this causes them to lose all of their cryptocurrencies
But how do the hackers enter the wallets that have a very high level of security?
Unfortunately, it depends on the ignorance of some people, not on software methods.
For example: When a message arrives in an e-mail requesting the private key, many beginners will respond to this message and send their key, which is really sad.
Here are some instructions that might help beginners:
1- Save your private key in an offline device
2- Distribute your cryptocurrencies to several govern orates to avoid losing all of them if one of the wallets is hacked
3- Do not reply to any message from an unknown source
4- Create an e-mail address for airdrops and Bounty campaigns
Do you have any other suggestions?
Don't use an online wallet to add it up also.
There are sites that would just require you to login in your usual login credentials (email and password), and pretty much those wallets are quite vulnerable to hacks.
For #4, when you register to an airdrop and you got an email for that, be cautious to the "Claim Tokens", etc thing.
Back in my days, a site that hides themselves as MEW (that's what I use for temporary claiming of tokens only) just to make you put your wallet file into their site.
