A few months ago, I bought XXXX ETH @ $21 per coin. I needed only 2 minutes of reading about Ethereum and Vitalik Buterin to understand it was BREAKTHROUGH.
In a couple of days ETH rapidly went to $56, WOW, and in couple of days suddenly dropped.

Everybody screamed "ETH is shit" and bla bla bla.

The carousel repeated again and again. ETH was long time trading @ $30-$40 per coin, and nobody EVEN PAID ATTENTION TO IT.

Everybody could grab ultimately cheap ETH, but few people (me among them) really believed in that project!

Everyone could have a chance, but no one used it.

Lots of people panicked, I saw a guy selling 25000 ETH @ $40. Yes, then it was 1M, but now it could be almost 10.

Moral:
Real investing is not about fast buying and fast selling. It's about believing and patience.

I sold my ETH @ $275 to invest all the money into MGO.
I believe in MGO and still believe in ETH.

All the rest doesn't matter.

Those who've screamed will keep screaming. Those who've made money will go on making money.

Good luck to you!
