Crypto is increasingly being seen as a possible hedge against irrational money printing of fiat. Bitcoin is more or less deflationary as the supply is limited and the expansion rate at present probably is outstripped by it's demand - hence the price increase.
As to why Bitcoin is rising stronger, well the media still presents it as if it's a singular movement. Only channels like CNBC even bother minuscule mentioning other chains like Ethereum.
Media is not that strong this time but we can actually hear many good news on social media which I think is more effective and the hype of Paypal makes bitcoin almost reach its all time high. Well, we’ve pause for a while and I know the trend will continue after this correction, many good reason for the price spike in the coming days.
