Depending how large your holding is of ACTM you very well might not be able to get your investment out without taking a decent sized hit so I hope that you are taking that into consideration when looking at buying into other securities. Secondly while I can't think of many better places to get advice on BTC investments you will be getting a lot of recommendations based on very little knowledge of what works at least in a traditional markets and most likely people trying to get you to buy into whatever they just bought into.
All being said and done however I would also be considering looking into of the the securities which offers fixed payouts such as
this or
this.
