There are many things most likely to consider whenever you're investing money in crypto..
These are:
1. Volatility of the Market.
2. They don't have the knowledge about crypto.
3. Negative news that they see or hear in social media/TV Media.
4. They were scammed and afraid to invest again.
5. Threats of hackers in the internet.
But users can also protect their computer from hackers by using:
1. Virtual Private Network for Internet Protocol
2. MetaMask Wallet
3. Not saving any private keys in your PC.
Today, many are afraid to invest in cryptocurrencies, this is understandable. I believe that the crypt for those people who are not afraid to take risks. But their risk may not be justified and they will lose their investment.
