Is it because of the large number of altcoins?
Conversely, a growing number of new altcoin types may affect bitcoin prices to increase, since altcoin values will not be valuable if they can not be converted into bitcoins in the market. the market movement of cryptocurrency is very sensitive to the many issues related to the restrictions that may affect investors' confidence to feel hesitant to invest in bitcoin, one of which there is news Google will ban advertising sprung up about cryptocurrency. maybe that could cause bitcoin prices to decrease.
Panic selling which is being done by most of the investors especially the newbies and the decrease in the demand of the bitcoin in the international market are the two major things which are playing a key role in this much decline of the market value of the bitcoin since past few weeks. Things will be fine but that will surely take time and till that time, we have to remain patient.
