you will sell only 5% of the tokens but I did not understand what 80% will be used for and this is very important for me as an investor.

Why ESAX Token total supply 10 Billion?

ESAX Token is not a token for public sale only. This is because a large part of it will be used in the ESAXC application. ESAX Token 80% of total supply will be used in ESAXC application and will not be public sale. Companies will be able to convert existing ESAXC Coins into whatever currency they wish and use ESAX Token in credit transactions. Only 500 Million ESAX Tokens have been sold to the public.

The tokens allocated for the ESAXC application are kept at this address and are all locked.
