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.
I am fully confident that this problem is caused simply by a lack of proper knowledge of the crypto market. After all, not everyone has the experience and understands all the excellent prospects for income and success due to competent investments. Therefore, such a lack of knowledge and fear of losing money does not allow them to begin their work.
