I agree with you that ethereum is one of the best altcoins to invest now, because ethereum is really popular and a lot of people is trusting ethereum so if we will invest on it i am sure that our money is we will be totally safe and i think litecoin is also one of the best altcoin to invest now.

I agree with hodll, IOTA and ADA, are really truly masterpieces, I don't know anything about WTC, Neo is not so great, because they have shutdown button, It's only great because you get gas, but with PIVX you get even more PIVX with staking and it's also private coin.

Ripple will be the best choice for you to invest now. EOS is a recent development, but EOS is in the top 10 coin market capitalization on the coinmarketcap.

Ethereum, Monero and Litecoins would be the coins which have a lot of potential to provide good returns in the future.
Ethereum provides a good platform for posting new ICOs and has gained its stability in the market. Also gaining a lot of acceptance in the market, the coin has way to go.
Monero provides complete anonymity in its transactions. It keeps the information  of sender and reciever private. Hence it is preferred for money transactions.
Litecoin with a market capital of $9 billion at the moment, has a lot of potential. And with its blockchain of 2.5 minutes, it is providing a healthy competition to bitcoin.

I think that the two most promising coins are NEM and ZRX, but this is not accurate, but they also bought them and wait for X! And there at your discretion, I advise you to analyze the data alt!

In just a month Eth rise dominant than others. The big possibility that eth will help you rich. The destiny of you to become rich in the future just incase you invest eth. The time frame to make it happen is not by very short of time.

Investing on ethereum and waves, because we think this is the 2 best altcoin to invest for, first is the waves we all know that waves is starting to make noise in the market and second is the ethereum the best altcoins

Ethereum is the best coin to invest as far I have seen there is lots of coins exists and also moving up and down trend but ethereum and bitcoin we regularly use either for payment or speculation . Ethereum more than that used to create smart contract.

I think you choose a very good coin, and a very potential coin to get a profit, but it will not be able to fully guarantee, because we know the price of a coin is determined from the exchange of buying and selling, so I can not determine its development in the future

if the goal is to choose two quality coins, then one of them must be an etherium necessarily. But the second coin should be chosen based on the fact, but what investments do you expect, short-term or long-term.
