Cryptocurrency is safe enough, but human is the weakest part of any security system in the world, so first of all, you need to be very careful about what you are saying and posting wherever it is happening, they can use everything to get your money!
That's true! Cryptocurrencies are as safe as you want them to be. By design, cryptocurrencies like Bitcoin are safe and secure against attacks from hackers. However, due to the carelessness of humans, they expose themselves to become hacked easily either by using online wallets, centralized exchanges, sharing their private keys, or even the inability to secure their computer with the latest antivirus software and a good firewall.
If people want their cryptocurrencies to become safe against unwanted theft of hacks, then they just need to follow the necessary precautions to avoid such things from happening in the future. Generating keys for a wallet without being connected to the internet is a good practice to help secure your crypto funds. In addition, using a hardware wallet would also protect you against undesired situations with your crypto funds. Therefore, by following such practices, you could avoid your funds getting hacked with ease. I myself, have been into crypto for a couple of years now, and have never been hacked because I always depend on cold storage, hardware wallets, and never disclose information about the amount of crypto balances I have. But, it's true that hackers always find a way to trick you and get your money, which is why, it's advised that you keep yourself updated against the latest threats to prevent your funds from getting stolen in the future.

Good point. The trouble that people seem to be having with crypto is because the onus is on them for security. Up until now, the only security we've had to deal with is the pin number for our bank cards and the login password for online banking. Now, things become more complicated. This is why people shouldn't be outraged if money is lost. The exchanges aren't perfect, they can only do so much to keep their environment secure. Although if they want to preserve their reputation, they should most certainly have a team of fraud prevention experts working full time people have so much money in those accounts.
