Honesty it solely depends on the trader/investor
The sole aim of investors/investing is to maximize profits.
And to the investor he/she doesn't/shouldnt care how they go about it.
As long as profit is yielded in the very end as opposed to loss, then it's fine/a successful trade..

Emotions/no emotions
It depends on exactly how they would be put into play,you wouldn't call a trader smart or an "Emotional" one simply because he traded with all the money he had
Thats being greedy and stupid,and doesn't always come out good...

Neither would you call a trader smart,and one who keeps his emotions in check,when he/she doesn't buy coins when the prices are low,but decides to purchase them when prices are rising(which is abhorred in trading)
That's simply being unwise..

Whichever term the both can be applied,as long as the trader keeps his head,and works to maximize profits, and suppress loss, then it's the right way to trade.
With or without Emotions
