the holding of cryptocurrencies has been a great source of price appreciation for those coins that are in great numbers off the market trading operations as the holding has created a means of scarcity and it is normal with the laws of demand and supply. holding also allows the price of coins to appreciate and that is also a plus as one can then sell off in a good profit margin.
The supply is not going to ever change so the coins could get expensive. I just want the coins on a crowded network to be able to do quick transactions .
