Sorry to hear about your 10btc. There is still time to get some before price goes higher.
My favs are: litecoin, dogecoin, ethereum, and dash. I like the community behind dogecoin.
Dogecoin does have a great community but it seems to be losing a little steam. GoldCoin is probably the most undervalued altcoin on the market at this time. Growing community, open workforce, and increasingly scarce. Plus our developer is a Cisco Systems engineer.
