So I had this idea of combining an "exchange" with a bitcoin faucet.
Right now the faucet pays out one of three things: satoshi's (100 every 10 minutes), green(long) tokens and red(short) tokens.
The tokens themselves pay out depending on where the moving average of the bitcoin price is in relation to the current price.
Basically green tokens pay out more per day when the price is going up (above the moving average), and red tokens pay out more when the price is going down (below the moving average).
If you can correctly predict the bitcoin price movement, then in theory you should be able know at which prices to trade these tokens to make a profit.
It's very much in an alpha stage right now; but please feel free to check it out
