-Security concerns: Fear of getting hacked or scammed.
Many CEXes have several layers for protection. Major one is demanding 2FA authorization. They also notice if you have suspicious ip activity and you have a freeze option in your account if you suspect something is wrong.
The volatile nature of cryptocurrencies: Losing funds due to the volatile nature of cryptocurrencies.
CEXes can't and shouldn't be doing anything about the valuation. It would be illegal price manipulation. Volatility doesn''t have anything to do with the fact it's crypto. Crypto prices just often is volatile
-Regulatory concerns.
What's the concern here? Many of them follow regulations.
-Poor user experience but to name a few.
That's a tricky question. We have come so far but we have so far to go. There was a time when users needed to understand what's happening under metamask, and before metamask, everything was so much harder. I am not sure how much we can dumb this down or if we could dumb this down enough when people are getting scammed with normal credit card scams as well.
