1) Ignore the people who just state a coin with no explanation or reason as to why they believe it is good to invest in
2) People have listed pretty much every altcoin on coinmarketcap, 90% of them will be wrong
3) I counted the coins mentioned and Monero (XMR) is by far the most favored altcoin of this thread
And here's my portfolio for now, I don't pretend to know which is the next big coin, I'd rather have a little bit in everything just in case something does go big
BTC, ETH - 70% of my portfolio
LTC: I believe it''s undervalued and much better than BTC, with upcoming segwit
ETC: Just have it from the ETH hard fork, might sell soon as I don't really believe in it
DASH: Good coin to adopt for mainstream use, still not sure what to think of the instamine issue
XMR: No 1 Private currency out there at the moment
PIVX: Dash 2.0, cheaper and without the instamine
Good for you. PIVX won't sustain its high price imo. It already had its shiny moment, maybe we'll see an other pump before dropping below top40.
If you check my list featuring 11 coins you'll notice all increased by up to several 100%. I forgot to include Decred which I luckily bought at $3 and $7... and imo will someday in 2017 surpass Dash.
I would be suprised if ETC increases a lot in value ever again. XMR and LTC still undvalued right now, especially XMR. LTC is not much better than BTC even if SW is adopted successfully because of the missing industry around it compared to Bitcoin. Well, we'll see...
If I'd write a list again, KMD and DCR would be in my top3 right now.
