Risks and self ownership

Hi all,

We've been thinking about that one for a while and can't wrap our head around it.

One - or one of the most important aspect of Bitcoin is its decentralization.

Using your keys, you are the sole owner of the funds. This, to us, seems to create a contradiction as the network is decentralized, but your access is now -excessively?- centralized ?

How do you approach this, and the new challenges this may put on a day to day life. You get your email hacked (or some other metadata pointing to you interest in this), they see crypto mails or deposit confirmation, and from a threshold decide on different attack vectors from virtual to physical.

Thanks for reading
