I agree that u get control like moving to your own wallet, but I dont get the point on how does crypto make it more secure than banks?

At banks, I get 250k insurance and if I use multiple accounts or wealthfront, that number easily jumps to 4 million. Can crypto get me more security than that?

I can see crypto as a good diversification argument, but not a "more secure than bank" argument.

Personally, I'm not comfortable with the volatility of the crypto market, so staying away.
