i am afraid Summer time is not going to be good this time. maybe i am wrong but when altcoins started rallying a while back that means by the summer they already will have had (?) a couple of months of pumping and all the pumpers have exhausted their supplies.
we may see a massacre by that time of constant dumping.


it is called "Confidential Transaction" if you google that term with litecoin keyword you will find better results:

not sure how far along this is though.
