Hey @cryptokash, congratz for the new miners. LTC will be around in the next years so it is an excellent investment.

I am no advisor nor crypto genious, but IMHO you shouldn't make a short-time investment in a crypto since we all know their volatility can be really high sometimes. Therefore, if you are decided to get 2 extra Antminers by august I belive the best option is pre-order them now and not take any risks.

If you are considering long-term alternatives, maybe Bancor white paper woth a read (ICO in ~3 days).
