Tricky question, BTC isn't like USD now and there are no legitimate banks to hold it and lend/ get you interest. HYIP's and the like aren't an option IMO and just a waste of money.
The other options are Trading against USD and buying/selling altcoins, even these aren't favorites to me since the market can move either way and it's pretty much gambling..
HODL and wait for the price to improve
