Actually we must have to consider this fact as logical statement if no one spends bitcoin.
Actually this cannot be happen. Because in market if no one going to sale bitcoin and if demand is increasing then price of bitcoin can reach to sky.
But this will never happen. Because till date bitcoin mining is going on and till 2145 mining will be continued. So till 2145 miner only get rewards for verifying transactions made within network. In no one spend bitcoin no miner will get paid.
If nobody spends bitcoin, it is useless and therefore worthless.
it will worthless because if it is no where in the market it will probably lose its value and hence it will be worthless. but i think it is hard tohappen because now bitcoin has customers in million so, i don't think it will happen ever.
I don't really think it would be worthless. If less people would use it, the price would go even faster because there would be even a smaller amount to be used, so a smaller available supply. I'm not sure which one drives the price higher though: people having it but not spending it or people spending it more than ever before?
