I also hold a very nice stake of $UNO and would prefer to continue our turtle model of slow and steady growth...
EDIT: In that regard, at least 80% of the crypto top 40 is down today. Where is $UNO? Up about 3%...

 

The crazy swings are due to very low price of UNO.
If I wanted to invest 10 000 USD into UNO think what happens to the price?
Currently we are not ready for bitcoiners massadopting UNO since there are plenty of bitcoins but very little UNO - out of which only a fraction is for sale.  
UNO definetely needs much higher price than the current in order to be a reasonable choice for bitcoiners to adopt. They do not want to move the price a lot when they buy (who wants).
Even with me when I bought UNO the price rose from 0.01'ish to 0.016, and I do not have a significiant stash (only a little over 0.1 % of UNOs that will be ever mined).

If I read it correctly the number one wallet holds nearly a quarter of all UNO ... and has never spent any, that doesn't seem ideal.

cryptsy coldstorage. It really isn't ideal that people can't withdraw that. We're chipping away at it though. It was once much larger. Last outgoing was 2 days ago. It always moves to a new adress when making transaction.

Thanks, makes sense for it to be an exchange wallet.  Though why does it appear to have no outputs?

Because it moves in one piece. Once something is withdrawn from it all the coins move to the next wallet. So the adress isn't reused once the privatekey has been used once.

Just this morning, the very first tiny tiny tiny bit of 'ex-Cryptsy' coin passed into strong hands. (But I gotta get community opinions before the project goes much further.)

Someone has done some tinkering, recently, to see how to get coins off of Megawallet.  Took hundreds off of there, and redistributed (sold) a majority of this to other exchanges, greatly improving UNO distribution, and thus health.

For example, you can't send Cryptsy 200 coins and then withdraw them, again, because that just drains your own hotter wallet on Cryptsy.  Basically, maybe at least 100 UNO must be purchased off of existing orders, bid or ask, but better (higher probability of Megawallet drawdown) from the ask, and then maybe it will withdraw from Megawallet, but it usually does, really.  (I suppose if you've had 100 or more UNO on Cryptsy for ~9+? months, pulling them off the exchange might work to draw down Megawallet, too.)

There definitely are different characteristics of traders that have orders that fill and result in Megawallet withdrawals when pulled off of the exchange, so we know Megawallet has many 'owners'.  Also, since we've been in the 0.008's, the Megawallet 'owners' have been very well behaved.  Potato traders are apparently going extinct.  

The takeaway from all of this is that UNO is quite healthy despite Megawallet; we've drawn down thousands of UNO off of Megawallet in recent times, and expect it to whittle down smaller and smaller over proximate months; and the conclusion is the same as always:  Buy coin on Cryptsy, often at a discount and in greater volume than are available on other exchanges, and TAKE THEM OFF OF THE EXCHANGE.

One might even be glad that there is still a place you can go to for buying 100's of UNO.

Megawallet?  Oh, we cool.
