uhh, the third line of your post?
Having false illusions of security towards traditional currencies (or other assets for that matter) are idiotic. I know it's different for each country but I have seen examples of what a corrupt government can do with centralized assets. Don't kid yourself that you're safe. ;-)
Bitcoin is not decentralized, don't kid yourself
Trading can and should be regulated, as for the bitcoin protocol itself, it cannot be controlled or taken over. It seems you forgot about the utility aspect for the pure reason that you, personally don't have one for it.
Regulated by who? And I do find uses for cryptocurrencies, I just accept and understand the fact that I will never be paying my rent with it
That line is: "I got my finances with my family/friends fully in bitcoin now." That means that I do the petty transactions among my friends and family in bitcoin. that's all. It doesn't mean that I have everything in bitcoin.
I can't seem to understand your stance on decentralization. On what level do you think it's centralized?
