Good post! Almost nobody is talking about the cons of cryptocurrencies. I actually like the technology which is brilliant, but I agree that we loose more control about money.
Bitcoin can be made unavailable by simply shutting down the internet or power.
Another thing to consider is, that in my eyes financial system is right before shutdown (could even take some years, but won't take too long). People won't accept a cashless world before things are so bad, that you have to accept it to be able to pay.
Almost nobody talks about this scenario being maybe created right in front of our eyes without noticing it too much.
very true!
