In my opinion, most people who are investing in bitcoin currently are new to crptocurrency world and they are riding the bandwagon, but surely, there are also smart investors who have invested lots of money into bitcoin and altcoins. Business minded people will not let their business go down, instead, take the opportunity to buy more bitcoin when the price hits the bottom. Although we may see the price of bitcoin to fluctuate, it is normal in the market. Bitcoin's development will never stop unless technology itself stops. Just hope for the best and believe in the future of bitcoin to be bright.
