The only problem with placing at 5 Litoshi now with over 800 LTC already there could be, that you maybe never get coins, because you're the last in the line then. I'd say 6 Litoshi is still a good buy at the moment. Even 7 would not be too bad. If you're investing long term, it should be relatively negligible anyway, if 5,6 or 7. OK, the lesser the entry, the nicer the gain. But who cares for Litoshis anymore, when Mooncoin will be at the old highs again ...  

Edit: Just restartet the moonchain-server, so it is accessible again - was stuck, as it seemed. But please don't you all check the suspicious address 2QgWwFic9H45Waeac7Gr4iveRp8UUuPAy8 at once now again, ok?  

Edit 2: You could also only pick the latest blocks with the highest "value out" (example1, example2, example3) instead of checking the whole address and will see, that most of them by far have been found by that address. See "Generation: xxxxxxxx" - this is the reward, that has been paid to the block-finder, it can best be seen in blocks with only 1 transaction. You can then pick a block like this one or this one, where you can see the aggregated rewards being sent to another address ( 2LKFcMY6Uk3qYqA4NYbgDS274ei2kx3BNf ), which I suppose is Cryptsy's, because when I observed it over a certain timeframe, exactly those amounts were some minutes later sold on Cryptsy. We cannot countercheck this at the moment, because Cryptsy's wallet is under maintenance. But I'm sure, as soon as Cryptsy reopens the wallet, all the summed amounts from over the last days will be sold there and after that we can see transfers like linked above being sold there again, too. If you check those blocks, where the aggregated amounts are transferred from that address in question, you'll most probably never see any single amount below 200000 being sent from there ...
Now try the opposite and check several blocks with lower and lowest rewards. I bet, you'll never find that address above in it as the address to which the generated reward-coins were going. That explains, why many miners are disappointed by the rewards they get over time. They simply are being cheated by that dodger, who uses a script to only mine the higly rewarded blocks, leaving the other miners with the little crumbs. Just like here: http://www.reddit.com/r/MoonCoin/comments/2h0p1e/mooncoin_can_we_have_a_serious_discussion/
Btw: I am - of course - not seeing Mooncoin going down or even disappear from exchanges because of this, like he does, but totally can understand his frustration for not getting the rewards he has to get, for dedicating his hashrate to the Mooncoin-network.
The next problem that comes out of this is, that sometimes it lasts quite a time until a new block is found, because the miners that mine on the smaller rewarded blocks have the same difficulty and the cheater is mining something else, leaving the other miners with their small machines with the work, to only chime in again, when there's another big block to get, so he can make out like a bandit. Therefore we not only need this solved because of fairness, but also for the functionality of the coin, so that all blocks are found fast and transactions will be confirmed as soon as possible.

Conclusion: We need a dev, who can help us with handling the wallet update to address this problem by changing from random to static rewards AND doing the necessary hardfork of Mooncoin.
