Like others have said, buy BTC, nest it through LTC, XPM, etc, and then close spreads (market making) to get 10% per trade, 1 trade every 2-3 hours (if you're paying attention) then multiply 5% for each nesting level. If you know what you're doing, you can quant trade altcoins short-term and get 30% per day pretty easily.

With $5000 you might incur slippage, especially on heavily divided currencies, so you could diversify and just run 5 $1000 campaigns.
