This could easily happen for Bitcoin, but the timeline given by McAfee I am not so confident in. One thing that keeps me hopeful though about McAfee's prediction is the fact that the biggest money in the world simply can't enter the market yet. I am talking about hedge funds and those players simply can't dump 5 billion into the market because that would ruin their chance at the best ROI. Therefore either they enter super slowly (accumulate over years) or buy OTC. I am confident that Bitcoin will reach a 6 figure mark somewhere in the journey, but as to when? That entirely depends on how quickly the big boys enter.
