Sometimes the high bounty is also a marketing strategy so that many people will join and help them to advertise as they have faith to the project.

And btw, this topic is all about bitcoin trading and set aside the topic about bounties and go to the right section to talk about them.

Now this is a mistake so many people make. Do not ever depend on luck as long as you are trading, depend totally on your own knowledge, how you want to play your card safely and that is all you will need. If you are banking on luck most of the time, emotions will always find a way to kick in. I tried it once and it never worked until I learned started trading like a pro and getting the best of the market. Once you can go about learning something that can help you make good decisions, then you should be fine.
Both experience and skills are very important. Experience is only applicable when you have been able to imbibe the skills first. Still, they both go hand in hand as time goes on in your profession and not just in trading, but in the general sense, you get the skills first, learn how to do it effectively and then you can start practicing. It is from the practicing that you will gain experience from the things you have been doing including your mistakes, which will then give you confidence in your trade as time goes on.
