Hey everyone I’m pretty new to the crypto currency stocks. Just a few quick questions I’d like to ask:

Is the reason that bitcoins price is around 15k per coin because the demand is so high but there is only 18 million coins availiable. Is this why there are other coins which are very high in demand but is only worth 1 dollar or less because they have billions of coins so even though there is high demand there is just an abundance of coins which means price is less? If that case is correct is there any other coins which will have potential to be worth many thousands of dollars because of high demand and low supply or was bitcoin the only real worth investment for holding because it will be the only one which multiplied from start to finish around 29000x?
