The crypto currency market is completely speculative! and the volatility of bitcoin is not bad or good! and this is a given
Well, I believe that the volatile nature of bitcoin is highly useful and great for those who really want to be successful with this currency. The way bitcoin increases in value in pumps, it would not be possible for many people to get involved with bitcoin if it keeps increasing in value all the time.
Dumps provide great opportunity to those who are making great profit or their livelihood by buy bitcoin cheap and selling it high.
