In my own opinion, its possible but its a community driven approach, not just BTC and Bitcoin cash but also in the next few months, a new bitcoin fork will also spike that is Bitcoin 2. These 3 coins would be of course on the top, and based on your statement, if it spikes or not in the next coming days, it would depend upon the community. There are a lot of factors to see, especially on the demand and supply , but the demand would greatly help the increase of prices on this stated currencies. It would happen actually but not suddenly, it takes months to years to count on. In fact, due to the recent news about the govenment adaptions of blockchain technology, i believe it would be possible.

Have a great day
