I do not sell my Ethereum since I bought at 50 € ($ 60) before the big bomb today I keep adding my wallet every time I can.

The Ethereum is following in the footsteps of Bitcoin, so if one goes up, the other one too.

I still think that he will be a nice competitor vs Bitcoin (but need time)

Really hope, I finally didn't sell and I will wait.

Bittrex has a large volume and variety of coins with a minimum reputation (no scam coins). It is the one that most people use today, very good customer support, expensive with the rates but people responsible.

Poloniex has the margin and the lending, you can increase your profits with loans and lend in exchange for a small fee.

Bitfinex I do not use it since the supposed "hack attack". It no longer gives me confidence so I don't recomend.

There are people who also use Cryptopia, I have not tested it but it has a great variety and nothing negative with the retreats but they have not a big volume like Bittrex.

 

This coin won't up... atleast soon.

It's a nice idea but have low marketing (volume is 37B in Bittrex atm) and these last days just down. I lost a nice profit but I'm sure it will still down so it's time to sell and stop lost.

I estimate it will reach 0.0012, then maybe it does a small pump.
