Does anyone know the answer to this as the top sites? I want to check historical prices that go back until the coin was created. Coinmarketcap and coingecko seem to be the main ones but some coins aren't available?
Like some coins, there is only a physical graph and not the regular high and low and open and close. How do you find this?
