Few years ago some economic specialist says Bitcoin is a huge bubble. why they said it? and what is the meaning of the bubble?
Well in economics, bubble is when a stock or in this case an asset goes up really high than it intrinsic value, then it will crash down. But economist or bashers they really do not know the intrinsic value of bitcoin. Since it is fairly a new technology they do not have any asset that they can compare it to. Bitcoin was already accused of being a bubble eveytime value goes up but look at its value now.
Bubble can be compared to a balloon full of nothing but air and its value can be questionable due to over speculation of many investors who only think of nothing but just the possible returns...once the investors realizes that they have been deceive into doing something they think can be a mistake...the balloon can pop leaving people behind with nothing but empty bags.
Bitcoin has been accused of being a bubble and a fraud especially if its value would dramatically rise. So far the warnings from well-meaning ( as well as ill-intention) people were just shrugged by the market. In my view, there is a mechanism which Bitcoin is using to check itself on a regular basis...there are regular retreats or dips which is adding more excitement to the market and is a way to correct itself.
As to the future of Bitcoin, nobody can be certain but that is true with anything in life. What tomorrow can be bringing should be left to time and chance...we can plan and we can speculate but only time will tell us what will really be.
