How to play
- Tap the big coin (or press Space) to mine BYTE, a made-up coin.
- Sell your BYTE for cash. The price moves all the time, so try to sell when it's high and above the dotted average line.
- Spend cash on machines, which mine BYTE for you every second, and on upgrades that make everything faster.
- Watch the news line: price pumps, crashes, whales and mining booms come along every minute or so.
- Grow your net worth (cash plus coins) to £1 million to become a Crypto Emperor.
Entertainment only. BYTE isn't real and its price is made up by the game. No real money or crypto is involved, and nothing here is investment advice. Real crypto prices can fall a long way, very quickly.
Questions
How do I earn faster?
Buy machines early: each one keeps mining every second. Upgrades such as Overclock and Liquid cooling multiply every machine, and the Sell bot sells for you when the price spikes.
When should I sell?
Whenever the price is above its average (the dotted line), and especially during a pump or after a whale buys. Avoid selling in a crash if you can wait. During an exchange outage you can't sell at all.
Does it keep going when I leave?
Yes. Your machines keep mining BYTE for up to eight hours while the page is closed or in the background. The price doesn't move while you're away, so you can sell when you come back.
Does the game save my progress?
Yes, on this device, as you play. If the game is open in two tabs, only one plays at a time so they can't overwrite each other. Use Start again to wipe your progress.
Is this a real investment?
No. Crypto Empire is a game for entertainment. BYTE, its price and its events are all invented. It isn't investment advice and doesn't follow any real market.
What happened to my old Crypto Empire save?
The game was rebuilt from scratch in October 2026 to make it simpler and more fun. Saves from the old version don't fit the new game, so everyone starts fresh.
