Less profitable than gambling.

Exactly. without that would give us much less chances to earn.
This is not actualy true. "Luck"based Gambling is mathamatically designed to favour the house however this is not true for 'Skill' based gambling.
Skill based Gambling is when you play a game against an opponent such as Poker, Backgammon etc and the house then charges a flat fee, known as a rake, to host the game.
As a poker player I win, over time, playing poker however as there is an element of luck, unlike chess, then i can play to the best of my ability and still lose to bad luck (known as a 'Bad Beat") or just being card dead.
The skill of being a poker professional is all about Bankroll management and the principles can be applied to Bitcoin and day trading. Basically when i play poker i only play with 2% bankroll.
I am guessing Day traders apply similar methods when applying their investment strategies
