You may be right LTC is a great coin BUT the github is quite It scares me.
DGB is a sleeper I think its been over looked for a very long time. Its time DGB gets its run in the sun.
and OMG is different I haven't done any research on it. I know Vitalik, is a huge part of OMG. And its a lot like EOS = Dan & OMG = Vitalik!

I also think there are a few others that need to keep our eyes on like
RVN
MAID
HOT - Its very different not a block chain Look in to it.
DASH - Masternode play
PIVX- Masternode play
PAC - Masternode play
SMART - Masternode play
NEM - Tokenized real world items.
TRX - The Pomp LOL!
This is a slim list of what I believe in.
