MAX (BTC) is the mathematical and statistical function that depends on fluctuations in the bitcoin rate and it gives out the maximum value of these fluctuations for the required period of time. It is not counted by any specific people. It is counted by a computer automatically on the specialized sites that review cryptocurrency rates. For example, on such sites as:  https://coinmarketcap.com or https://www.coingecko.com  So we take these numbers in automatic mode from there.  Not a single person from the EurBit team counts these numbers, does not approve and has nothing to do with them at all.
