I think in the next bubble Bitcoin is going to reach into the top 3 currencies worldwide. It being at the number 6 position just goes on to show that Bitcoin is unstoppable. Also many other crypto currencies are entering the top currencies club which is good for the crypto markets. Bitcoin will become unstoppable once it reaches in the top 3.
But we also need to understand that 15-20 billion US dollars will be enough to bring down the rate of bitcoin to $ 100 for 1 bitcoin
