If it became some type of global reserve that's possible, but I really can't imagine any government or central bank gritting their teeth and hitting that buy button on Yobit.
If it became the de facto reserve for regular people that's conceivable too. In my entire life I have only met two people who owned any gold. I think it would require a few more decades though.
If you are saying that bitcoin will need few more decades to hit $1 million, then I think you are right. It is quite impossible to reach the $1million target in just one decade. There may be a general adoption of bitcoin but there will be resistance. This resistance will slow down bitcoin price increase and might pull it down again and again.
