There is something that needs to be improved that is not a problem in Bitcoin itself, but in the ecosystem. I think users need safer wallets, so they will not be forced to buy hardware wallets to have a higher level of safety.
The look of the bitcoin wallet that is now available is relatively safe.
as it is already available with two security levels like 2fa.
the 2fa lock is only a code holder that can be opened, and it's in very decline it's proven safe.
