Most of the old coin start at a very low rate on like the new coins now that what to raise many millions in dollar and the rate of many are s hype that most have more value than the old coin, but I still believe in some old coins with potential and no matter their rate or value in market now still very low and in future will be huge
It cost people money to have the coins listed in on an exchange, the coins have to be on there for a reason.
