I think that bitcoin is currency I mean cryptocurrency not only currency what means that bitcoin price is fast changing what is good for investing in bitcoin so I dont think that we can call bitcoin investment when cryptocurrency=investment.
It seems to me that the rapid change in prices can only scare off investors in bitcoin. Such jumps is dangerous. The price may increase and an equally fast fall.
While the volatility on bitcoin price may scare off those investors that prefer to take safe investments for many bitcoin offers the opportunity to earn big in a liquid market that moves extremely fast and give to them the best chances of making money fast.
