ETH because the ICOs are here to stay!
I also thinks that ETH is best option for the investment , but here we need to stay with our investment for long run investment and also we need to make investment in another coins also because to get investment with another coins also a better opportunity for us to start perfectly with trading .
Here my opinion and analysis is saying that we should trade with atc , bch , bcc , dash , ripple , ltc , doge , siacoin , reddcoin , creva , posw etc .
These are those coins which have daily fluctuations of the 3-4% -+ , so easy to make better profit with these coins .
Here i listed multiple coins because the main reason is of the lowering the risk of trading loss because sometimes we bought a single coin in bulk and that particular coin goes much down , so we needed for long time for that coin to rise and recover loss and get profit .
