I've found some really good investments on
www.litecoinglobal.com which is the litecoin side of btct.co and also run by burnside.
LTC.MINER
BUY-A-HASH
These 2 mining bonds in particular I'm invested in and so far are returning very good dividends each week

If you're adverse to converting your coins to litecoin then I would recommend ASICMINER-PT or TAT.ASICMINER shares on btct.co the added liquidity of that exchange is a really strong positive and as many have already said ASICMINER is a solidly performing stock.
