MONEY is the riskiest of all risk!! They tell you to take the riskiest gambling with your life.
I do not understand what you are trying to convey here because except money, how you are going to risk in economic way? Because, in our financial life, we measure all the actions and efforts in money value then risking in money also makes sense. Hence, risking in money may not be considered as gambling. Gambling is something else where you risk purely based on your luck (which is beyond our efforts and control).a wise person won't just go blindly when they are risking something
Blindly risking will not have any huge differences from risking-all-at-once. Risk management principles should be followed everywhere when we risk so that we could come back to recover losses and then start afresh toward profit making. 
Just do not forget one simple thing, that not all people have enough patience to work with small amounts of money to earn as little money when there are a lot of stories about quick enrichment around. Therefore, we can talk as much as we like about limits and about some caution, but there will always be a temptation to risk a larger amount for the sake of getting more profit. Therefore, the absolute majority of people perfectly hear the voice of their reason, but unfortunately they do not always listen to this voice, hoping for a miracle.
