When we are active internet participants, we have many problems, difficulties and dangers ahead of us and when need to steer clear of all from it. One important topic is identity theft, where your identity will be stolen and abused by criminals online.
We can't help this by doing everything you said because all of them are now like a norm to have access to your money for being someone that earns from online. It must not necessary be crypto but other means of earning online. If we don't enter addresses online for shopping then how do we get our items delivered to us at home or are you saying we should avoid online shopping completely? It's not possible and there are just things that they have become a part of us that we can't just avoid them anymore.
What we can do is to just avoid letting out our sensitive information on different platforms, we have to avoid trusting random sites with our credentials. You can't prevent identity theft but you can limit the information they have access to by being selective of what you give away.
