After all, what do you want to see as a replacement for fiat, do you have any suggestions? If you are wondering that bitcoin has any chance to overcome the fiat, then you are wrong. Blockchain network is not ready at all to maintain under such a massive traffic, and the another issue is that the fees currently are exceeding the reasonable amount of money spend for commison. You cannot buy some cheap things ( e.g matchsticks or cans with drinks ) because the price would increase dramatically, because of a insanely high fee payed on every transaction
Things may change in the future
And they may change fast at that. The measures which would fix the scalability (as well as high fee) issues are already here, they just need to get implemented. Bitcoin is different from fiat, and it is a difference of kind, not of degree, and after these measures are taken, Bitcoin future adoption would only make it more fit and suitable for even wider adoption (since it is decentralized and supported by network itself). And this is where theory meets with practice, since money works better as money if it get more universal acceptance. In this sense, Bitcoin is absolute money since its adoption facilitates further adoption in a chain reaction manner making its transactions faster and cheaper
Great point deisik. I always love to read your posts =)
