Do you know why bitcoin going so much down?
I think because some investors are more interested now in altcoins, there are altcoins that also has a potential to rise in the future and it is possible because bitcoin is too expensive to have right now. That is why maybe some investors are putting their investment in some altcoins.
Bitcoin is getting down but that's quite natural for it since the currency is too volatile and fluctuations in the price are common for it. That could also be a reason for the people may be switching to some other altcoins as still the currency is retaining a higher value thus making it too expensive for the investors to invest in it and that factor in some way or the other is affecting its value...
Fluctuation of the price depends on the people's demand and supply that's why other users are switching to altcoins. Yet the transaction fees are getting higher and higher due to the demand of the mining fees everyone could not help it but rather wait for the upcoming LN but LN is under in development and everyone couldn't wait for it to release. Some FUD or fake news will affect also the fluctuation of the price because people will tend to panic selling if they see that the price is down. Price correction does a big impact to Bitcoin because of it's constant rising.
