I know bitcoin is widely accepted and even many big merchants have now started accepting it so it's high price may be justified but why the prices of other cryptos as mentioned above are even more than a cent?Who uses Dash or Litecoin and where?
generally i don't think altcoins have any real places to be used, especially the new unknown coins you find, they are just for pump and dump purposes.
but coin as old and useful like litecoin can be used in real world shops to buy things and that may be one of the many reasons the price of LTC is stable and high after these years.
