I don't really understand why there is a limit being set for any cryptocurrency. The coins, because of these limit of the volume makes price movements possible. With these movements also volatility can come in. So my thought is this, because the changes in values brought about by the changing supply and demands for a certain coin causes volatility within hours or maybe minutes that becomes a big factor for users of coins to be hesitant in using the coin as payment system, would it be helpful to set the changing price of coins per day only so that any use for the coin as a payment system within the specified day will make the price stable for a time and would allow or give the users enough time to use it as payments and be safe from loses due to volatility that strikes anytime?
