Blow-up simulator

Real bitcoin prices, fake money. Pick your leverage, pick a side, and find out how long you last. Nothing here is real trading — there's no account, no deposit and nothing to sign up for.

Prices are live from Binance's public market feed, straight to your browser. Fees are modelled at 0.04% per side; funding is ignored. Maintenance margin is a flat 0.4%, where a real exchange raises it as the position grows. Nothing is stored on a server.
