Well the FED will print a lot of money ( as usual) to save from the crisis. In the end, it's the American citizens who will pay back the debt. So we are safe. If not we have a plan BTC ( the € plan)
 

too hard to say what will happen but my guess is that the centralized bodies will introduce their own "revolution" in money, which will be more of the same, controlled and centralized. The masses eat up deception very easily and will adopt that, along with the tyrannical financial surveillance that already exists, bitcoin and other true open, decentralized crypto-currencies will continue to appreciate in value when compared to the systems less preferable form of exchange, as less and less people will want the digital fiat.

I guess if you take the dollar and fiat out of the equation then Bitcoin will come the new standard and you won't compare it to any other type of currency.  You will just associate the price with items you normally purchase.  Same as we do with the dollar now. 

There is no how infact not possible that Dollar will die rather both bitcoin and Dollar will be moving hand in hand. The amount of energy needed  for mining is not so enormous. What is the wattage of most of those mining  machines ?  There are not energy intensive as such to disrupt the energy need of the country. 

Bitcoin isn’t just an asset to sell for profit, but Bitcoin is also a medium of exchange that can be used for transaction just like FIAT, Bitcoin also has its own value. But I still doubt if Bitcoin should replace the Dollar later with the current state of Bitcoin, easy example is the number of transactions per second.

Nothing  US dollar do to us. We only need to eat our own work effort only needed. Please do not go with the fiat usage all the time. Transaction will be same for everywhere in this world for using cryptos but Fiat cash will fuck you for sure.
Ignore Fiat and make money with the  cryptos and save fees you bear.   Yes, precisely, this is what I think the next step will be as well. They will find an alternative. A nice alternative that is more convenient and safe for the masses, and they'll spin it in such a way that everyone will eat it up without question. Just like everything else that they've been forcefed.

This is why the concept of bitcoin has so much value, but the application has to be realized before the fiat is defined as useless. It's already well on its way with China and Russia purging their reserves of USD and the IFM talking down the dollar as if they've got some other grand scheme in mind. This could be it!!!
