Buying on listing day?
Read these lines of the listing announcement first

“HYPE is a relatively new token that poses a higher than normal risk, and will likely be subject to high price volatility.” That warning comes from the exchange itself, inside its own listing notice for HYPE, published on 24 September 2026, a few paragraphs below the trading time.

If you are weighing a buy on listing day, most of the advice you'll run into is about getting in before the listing. The notice itself rarely gets a close read, yet it holds the details that matter on day one: when trading starts, when deposits and withdrawals open, when airdropped tokens land in other people's accounts, how much of the supply is actually circulating, who has to pass a quiz first and which regions are shut out.

This piece walks through those lines. It won't guess where the price goes, and it won't tell you to buy or stay out.

01Can you buy a new coin on listing day? Find these six lines first

Listing notices are grouped under New Cryptocurrency Listing in the announcement centre. They run long. The lines that bear on day one are these:

We read them in a different order from the page layout: withdrawals first, then supply, trading time last. Everyone already knows the trading time. The other two are the lines people scroll past.

02When do deposits and withdrawals open for a new listing?

In the AT notice: “Users can start depositing AT at 2025-11-27 10:30 (UTC).” Then: “Binance will then list AT at 2025-11-27 14:00 (UTC).” Deposits ran three and a half hours ahead of trading.

In the HYPE notice, withdrawals open about a day after trading. Trading opened at 11:00 UTC on 24 September; the notice says “Withdrawals will open at 2026-09-25 11:00 (UTC),” and adds that “The withdrawal open time is an estimated time for users' reference.” So for roughly the first day, the token could come in and change hands on the exchange, but whatever you bought stayed put. If the withdrawal page ends up showing a later time than the notice, the page is what counts.

One more line that tends to get skipped: “Trading Bots & Spot Copy Trading will be enabled within 24 hours of it being listed on Spot.” If you normally trade through a grid bot or copy trading, don't count on the new pair being available there at the open.

The gaps change every round, so work them out from the notice in front of you:

• Deposit lead time = trading start − deposits open (3.5 hours in the AT round)
• Withdrawal wait = withdrawals open − trading start (an estimated 24 hours for HYPE)

The deposit sentence in the HYPE notice deserves a second look: “Users can start depositing HYPE in preparation for trading one hour later.” The natural reading is deposits now, trading in an hour. The Chinese version of the same notice, though, attaches the hour to the deposit channel itself: deposits open one hour later. The notice settles which one wins — “There may be discrepancies in the translated version of this original article in English. Please reference this original version” — but when the original can be read two ways, the practical move is to check whether your own deposit page lets you pick the token yet, rather than counting hours from a sentence.

03Who already holds a new token before trading opens?

At the moment spot trading starts, the people with tokens to sell are not only the ones who just deposited. The AT notice spells it out: “the new token will be distributed to users' Spot Accounts at least 1 hour before trading starts.” That round's HODLer airdrop was “20,000,000 AT (2% of total token supply).”

Some holders got there earlier still. Before the spot listing, the notice says “users can now trade AT on Binance Alpha Market,” and once spot opens, “Users will be able to continue to sell AT via Binance Alpha.”

Divide the two figures from the notice: 20,000,000 airdropped ÷ 230,000,000 circulating at listing ≈ 8.7%. Close to a tenth of the tradable supply at the open had been sitting in other people's spot accounts for at least an hour, and that is before counting anyone holding through Alpha. Whether they sell, and how much, the notice doesn't say and we won't guess.

How those airdrops are distributed is covered in how to catch HODLer airdrops. The decision on the other side of the trade, holding an airdrop at the open, is covered in our piece on selling a dumped token at the open.

04How much of the supply circulates at listing, and why does it matter?

The AT notice has a line headed “Circulating Supply upon Listing on Binance: 230,000,000 AT (23% of total token supply).” Put that next to the airdrop line's 2% and the total works out to 1 billion AT, with under a quarter of it tradable on day one.

That one line drives two numbers people tend to blur together:

• Market cap at listing = price × circulating supply at listing
• Fully diluted valuation = price × total supply

For AT, the second is 1 ÷ 23% ≈ 4.3 times the first at any given price. Listing-day price discovery happens on that smaller slice.

As for the other 77%, the same notice flags one tranche: “20,000,000 AT will be allocated into future marketing campaigns 6 months later.” For the rest, you need the project's release schedule; reading an unlock schedule shows where to find it. The lower the share circulating at listing, the larger the part still waiting outside the market.

05What does the seed tag mean, and can you still trade it?

Both notices carry seed tag rules. Being tagged doesn't block trading; it adds a gate: “To gain trading access to tokens marked with seed tag, users will need to pass the corresponding quizzes every 90 days.” The quiz expires, so passing it once is not the end of it. The notice also says “A risk warning banner will also be displayed for all tokens with the Seed Tags.”

If you go to trade a tagged token on day one and find you have no access, an expired quiz is the first thing to check. The seed tag is also a separate mechanism from the monitoring tag, which we covered in the piece on listing rumours.

06Why can't I trade a new listing from my country?

The HYPE notice includes the line “Currently, users residing in the following countries or regions will not be able to trade the above-mentioned spot trading pairs”, followed by a list. That list can differ from one notice to the next, so read the one for the token you are looking at. If your region is on it, you can't trade that pair, and this site will not suggest ways around it. Follow the rules where you live.

One thing is missing from this piece on purpose. Figures like “new listings drop X% on average on day one” circulate widely; we could not trace any of them to raw data we could check, so none are included. How a particular token trades on its first day is only known once that day is over.
