All what I can say is that, for now Bitcoin is not outdated by any other 'cryptocurrency'. But in years to come, if no other crypto stands up to beat bitcoin in the game then it can still stand. Modern technology is always increasing; if another coin emerges to give what bitcoin didn't give, don't be surprised that this our favorite coin will be outdated. Or else if it is constantly update to match new modern technology.
All crypto currency status are temporary, something can happened anytime in market trading. Base on the fundamentals of Bitcoin compared to any other ALT coin still being outdated by any other crypto currency in the market today remain to be seen.? Bitcoin was beaten up so badly yet it remain standing as of today. After the market glitz in the past few week, it recover to a better standing in the market today. The prices goes up and down yet it stabilized wit the good fundamentals, increase volume of shares, investor are happy with their gain on the said project. With the global acceptance on crypto currency on market trading as posted,Bitcoin can not be out done yet by any other currency.. i am optimistic that Bitcoin will remain standing until the end of this year.
