There is no question that bitcoin is evolving and whether it is in the direction that it should be or not that can be subject to some discussions and debates. Soon we may witness bitcoin to be the viable platform leading the way in the global payments industry and possibly diminish the strong leadership of PayPal.
paypal?.. really?(facepalm)
paypal is not a currency. its just a company.. basically a bank brand.
its like saying will bitcoin have issue overtaking UK barclays bank
firstly paypals main niche is to be a bank account linked to ebay usage. to add to this people are already moving away from ebay and thus paypal by using amazon, alibaba, aliexpress, facebook and other product marketplaces.
in short paypal and ebay are already losing grip of their own niche.
(ebay has 170m users. but amazon has 300m.. ebay has already lost its top market place status)
as for the payment transfer side from user to user. just like banks there are many competitors. heck im in the UK and i can pay anyone in the uk for free and within minutes(seconds mostly) just using my bank so i dont need to use paypal just to give someone else ££
bitcoins limitation is not popularity, its not lack of access to get coins. its actually the limitation of number of transactions a day
no promoting more adoption of people to us btc will fix the transaction limitation.. infact with 600k transaction limit. if there are more than 600,000 people wanting to use it daily, realise they cant. those left waiting for a confirm will just think btc is useless for thier purposes and just try something else.
put it this way. if amazon (current leader) decided that tomorrow it would allow only 600k transactions a day. do you think it could service 300m customers. do you think amazon would remain top?
