Every coin gets its own long vs short market. You put your own SOL behind it with a locked long.
Your buy happens in the same transaction that creates the coin, so nobody can buy before you, and the chart starts right away. You can sell it any time from the coin page.
Your SOL stays locked behind your coin for 1 hour. Its liquidation price is public on the coin page. If the price falls to it, your stake is gone and the coin is marked as rekt. If it survives, you get your SOL back.
Launching costs about 0.021 SOL in network fees and account deposits, plus your long. It does not guarantee liquidity or buyers.
