The main reason is manipulation. Crypto is being manipulated and I realise it.
Right now there is nothing to do with it, so I hope in future something will be changed about it,so let's talk about our actions.
What should we do?
Along sides manipulation, there are many other reasons as well. Due to its high volatility, any bad news can negatively affect the price. Many people consider BCH fork the main reason behind this crypto downtrend.
US justice department is currently working against this price manipulation issue and hopefully, so thing better will happen in near future for the crypto market.
