Good coins to hold long term in my opinion are:
- Bitcoin
- Litecoin
- Peercoin
- Dogecoin
- Namecoin
- LTBcoin
- Foldingcoin <snip>
The bolded above I agree with. The rest are like WTF coins, and I wouldn't hold them if you paid me to. But I'm just pessimistic about altcoins in general now. Too much risk, and the market seems to be very saturated. You could probably make a fast buck on all of the above, but long term (except for btc, doge, LTC)? I doubt it.
I base my list on coins that have been around a while and have some credibility. I believe long term that coins with strong fundamentals will surpass those that do not.
I remember around January 2013 when altcoin trading was starting to gain steam, people where buying and selling scam coins to make a quick buck. Now if they had taken that money and put it into litecoin/peercoin/namecoin instead they would have seen returns to the tune of 30000% that november, but they decided to invest in "hype" coins and make chump change in comparison.
I am not saying that this will happen again but i prefer to invest in something that has long term planning and some goal rather than IPO/ICO which exist only to enrich the devs.
