I believe that this is all because of the big traders who are very active in trading. and this is the impact with prices that change fast. other with the increasingly difficult altcoin untik can crawl up, to a higher selling price. this is very troublesome altcoin traders
Active traders is one of the biggest contributors as why btc price is increasing. And ofcourse the demand is increasing that btc price becomes high. Altcoin price dump when btc price increase, but in contrary altcoin ofcourse will go up. So I think bitcoin will continues to go up.
I agree, its basically what the law of supply and demand was saying. Because there were active trader, the demand is also increasing. More and more people are now engage with bitcoin because of the popularity it is gaining from the mainstream media. Other factor why its demand is increasing is because of the recognition of the government, which makes more people trust and invest with bitcoin. I also heard well known personalities getting involve with bitcoin, tgis gives instant publicity to people to attract more investors.
