For the first one. Gotta agree, normal people (non-technology) wont be investing in Bitcoin. Most of them are afraid for the rapid changes in the exchange rate. And.. some of them can't understand how Bitcoin work. Unless Bitcoin is value stable, else, people wont be investing in it.
Volatility, a heaven for the majority of traders.
Exactly, it';s this volatility that makes it possible to profit, only people obviously don't like it when it doesnt go the way they want it to but that's part of the game that they need to understand. The hodlers and long term believers don't really care about minor fluctuations.
