tokens offered by third parties are considered fraudulent if they are not authorized and are not listed as an approved seller, therefore you are absolutely right in your statements.
I heard such information that for some reason at a certain stage I will not be able to view the balance due to the audit of tokens. What is the reason for this and when will my balance be available to me?
everything is simple, my friend. You can view the balance after the purchase of tokens, but before the audit. An audit is an event aimed at accuracy before the distribution of tokens.
now I understand why this is needed. I assume that after the end of the audit everything is normal, I will receive my tokens on my wallet and will be able to use all the functions of Troy Vault.
