Nice post!
And You are right :)
I speak a bit from experience - I've been manically trading for the past two years. If I'd just held ethereum and done no trading I'd have made a better return :)
But, unfortunately that really requires a least a bit of hindsight! If everyone knew ethereum was going to be worth this much, then everyone would have bought it at the time..and no-one would ever have sold it! ;)
