I started with the MLD for just 4 weeks ago (poolmining via litecoinpool.org), so one learns fast. With such a small hashrate, one could consider if solomining (not sure how to setup but there are some messages on it in this thread; the bfgminer that works for the MLD2 does not support solomining, so there are some workarounds needed I recall) is a more interesting alternative. Then it is more like a lottery and for sure the chances of finding a block are higher than anywhere else.

At 2.3Mh/s for a year you will earn 0.11LTC (poolmining at current difficulty, in practice less as difficulty will rise through the year).
However there is a 0.8% chance to mine 25LTC in solominig within 1 year. 0.008x25 = 0.2LTC, so that seems a good bet, and 25LTC x say 250$/LTC = 6250$ at a chance of 1:125 and an investment of 65USD is a return of 6250/65/125 = 77% is not bad. You don't find that in any lottery. Of course there is 99.2% chance that after 1yr you sit with nothing other than the investment of 65$. Once can do worse than that, especially with just one MLD2.

Just some thoughts on how to make the most of a MLD2  Others can probably pitch in here too with their views.
