Well based on the price of bitcoin today or this year it can't be replace by another cryptocurrency,, actually it can but it will take a decade just to replace bitcoin in its place, every time passes by the bitcoin price is increasing too meaning it is impossible but in other side it is possible too
Price is never going to lay any affect on people actually using the currency in the least, so that's something that you should simply just not care about at all. Price could just be made out of nothing, the only thing that's going to change the price is going to be the buyers and sellers wanting to use the currency. I could make a rando shit coin today and buy it for 10000 and then make the price start at an insanely high price.
Bitcoin isn't going to be replaced by another crypto though, this is simple because Bitcoin is going to be having everyone using it on a daily basis while all of these other cryptos are just having tons of trade volume and that's it. If we compared the amount of REAL usage in bitcoin and these other shitcoins it'd be one of the funniest things to see, as Bitcoin is being used while others are just trade shit coins.
