Due to some genuine reasons market is crashing again because of crackdown on exchanges in japan. In some article I read last year that this year will be the year of regulations and it has been proven right.
Russian prime minister has set a dead line for its finance ministry after which cryptocurrency will be legalize in Russia. This news has also activated the traders to sell their bitcoin so that they could buy it at low value.
Each time when some news spread into the crypto community traders start selling their bitcoin along with those people who really got affected with the news. Some fake news also become so popular that very less users show courage to deny the news and it becomes very easy to crash the market when every one is ready to sell after hearing any kind of news.
Holders are those who believe in the technology they are willing to pay taxes and they know the worth and future of bitcoin very few people are holders but they will be successful in the long run and that would be the real success as they will be able to say that they believed in the technology since beginning.
