Issuing a token on the TRON Protocol can be done by anyone
who has at least 1024 TRX in their account.
When a token is issued it will be shown on the token overview page.
Users can then participate within the issuing time and exchange their
TRX for tokens.After issuing the token your account will
receive the amount of tokens equal to the total supply.
When other users exchange their TRX for tokens then the tokens
will be withdrawn from your account and you will receive
TRX equal to the specified exchange rate.
