Have you already entered the stock exchange or not? That is, a token can only be purchased through a purse? If I don't have a purse, then I cannot buy your token. It'sa pity of course, if it is.
Are you talking about the stocks.exchange website? 401K has no plans to list there.
You can purchase 401K Coin at CryptoBridge:
