That's where altcoins are useful. When bitcoin's value are so high that giving a tip is such a waste you can use altcoins. Bitcoin is not the only cryptocurrency. And bitcoin will not be on top if there's none on its bottom.
why consider it as a garbage? because it is not useful? or youre not just using it the way it must be?
but in others opinion its not useful because its just a digital currency just like the others they have different kinds of uses
so why do you say bitcoin is a garbage of there are also currencies below it
