Impossible Bitcoin will never be worthless the real question you should be asking is wether Fiat currencies will be worthless
Fiat and bitcoin both are not going worthless, both have on position. Actually, it is common thing, when bitcoin price is going to down then people think about bitcoin that bitcoin is going worthless. In my view, within few months when bitcoin will take position, then we forget this thing that bitcoin was worthless.
hope it is as you say. well, we know that the function of bitcoin is to be an alternative payment, and this can be compared with fiat. well, in this case, we know that developments will continue to occur, and make the position of bitcoin stronger. I only hope that this development continues into the future.
