Sorry sir, what you try to say here ? your post tittle sound confusing, and i allready read that bitcoin whitepaper long time ago when im still in highschool
I dont even try to read the whitepaper but i have felt that bitcoin is the best one.
However i also confuse what the op try to say.
Try to do a 15$ transaction with BTC, then try to do a 15$ transaction with BCH. After this experiment you will no longer feel Bitcoin is the best one but a doomed non-currency.
Bitcoin's fee is more higher than bitcoin cash specially if you will just withdraw a little bit in your account. The used of lightning networks ease this problem however maybe someday it will lead to a centralized network. Assure the fast and reliable in bitcoin someday.
I think bitcoin cash aims to dethrone bitcoin. Well, it is possible to happen. Bitcoin cash has the potential to lead the market.
