besides ethereum, it would be EOS, Ripple and Litecoin

The best way would be splitting your invesment in multiple altcoins, it is same as not putting all of your eggs in one basket, there are other coins like Ripple, Litecoin, EOS and TRON. A investment in only single altcoin is a huge risk factor if you lose it all.

According to the current trends, it would be Ethereum, Ripple, Litecoin, EOS and Stellar/Verge.

looking at the current developments of EOS, it will be one of the Best Competitor to Ethereum, Also NEO, Cardano can bring some tough competition to Ethereum.

altcoins are not that stable yet, but the most stable from rest are Ethereum, Ripple and Litecoin

EOS would probably the coin for 2018, it looks promising and might be a very good technical competitor to Ethereum

it would be ripple. also ethereum and eos is good.

If you are doing daily trade go with ripple, and if holding for long term Litecoin would give you good returns.

I guess EOS,  until something other coin comes up.

 yes, holding EOS seems to be good choice, given the model of the blockchain, it looks like it has some interesting enhancements over Ethereum.

A good strategy would be hold more of stable alt coins like ethereum, ripple, litecoin along with Bitcoin and then day-trade with other alt-coins that
show movements frequently.

yes, there are still good ICO's coming, do a good research to find it is legit before investing.

I use the following app to track my portfolio https://getdelta.io/ it directly imports transaction data from many popular exchanges.

Although this a forum, I would count on the following three social media platforms: Bitcointalk, Telegram & Twitter.

Buy and Hold Altcoins, Bull-Markets will come, patience.

 Ripple definitely has a good future, the management at Ripple is always looking out for new opportunities to make a impact in Banks and other financial institutions. Buy and Hold.
