Re: What is the most influential factor that triggers bitcoin prices to fall down?

In my opinion, the most noticeable effect on the drop in the price of bitcoin is caused by negative news about the crypto currency. Bitcoin reacts very sensitively to such news, because this changes the ratio between demand and supply, and it depends entirely on them. Recently, we could see this clearly when the bitcoin course reacted sharply with its fall to negative news from China, South Korea, India and other countries.

I think with low supply and high demand means price increases, but if supply is more than demand then it triggers the price to fall. And I think the bitcoin value is based on market supply and demand

I believe so, yes. Bitcoin's prices can really be affected by the number of supply and the number of people that wants to use it or hold on to it. But this certainly doesn't mean that the price of it relies on that alone. Clearly, economical issues also affect the prices of not just bitcoins but every coin out there also.

Bitcoin presents a variety of opportunities that did not exist prior to its development. Yet, it has failed as yet to convert investors concerned about its potential rate of adoption as an alternative currency. Recent acknowledgement by the IRS that Bitcoin is an asset for tax purposes has clarified the situation for investors, and the promise of frictionless value transfer suggests innovative use cases in foreign direct investment. In the near term, much of the volatility will be driven by investor perception of the ability of gateways to safeguard individual holdings and provide for a reliable store of value as adoption increases.
