You have claimed three issue.
1. Trading
2. ICO investment
3. Bounty.
From my personal experience, I want to give you some tips.
1. Trading: Trading with cryptocurrency is very risky as well as more profitable. But before investing you have to know the market. This market is so volatile. To make profit you have to focus on short-term investment.
2. ICO: Yes, I agree with you. There are lots of ICO out there but not all ICO is SCAM. Might be some ICO become unsuccessful. But it is true that the success rate is low. So, you have to do deep analysis of an ICO project and have to choice 5-10 good ICO.
3. Bounty: For doing bounty you also have to have much knowledge of ICO projects. When you will start to doing bounty, gradually you will learn to choose the perfect and payable bounty.
Thanks. 
Let me also share my own experience.
1. Trading - Crypto trading will need a lot more skilled in Technical Analysis than Fundamental Analysis. So you need to learn how to see the support level, the 20 or 100 SMA etc. to determine where the moment is a good time to buy or sell. I do know of a few people who are youtube influencers, are giving quite good calls and you can consider watching them. Personally, i dont do swing trading, i am usually buying and holding coins that i believe in.
2. ICO. You have to assume that 90% of the ICO will end up with nothing. Even the remaining 10% of the ICO, 8% will be in the red, and 2% will be the one that give you the profit. So far, I have managed to get quite good in ICO because i happened to invest in the boom market. So the period of entering the ICO is also very important. Recently due to the bear market, those extremely good ico that i invested in also turned up to be at a loss. Some of these are Oneledger, Rate3 and many more.
3. Bounty is the safest way cause you dont need anything to get involved, so the only loss you can get is your time gone. However, out of 100 ico bounties, most of them are fake or cant even rise the soft cap. You will end up getting nothing. Yet, if you manage to pick a really good one, you can earn a ton of money from it. And also do take note that some ico gave out their tokens, but they did not bother to get the tokens listed and thus the value of the tokens can drop 90% of it price.
(Do check out my bounties campaign and i can promise you that i give extremely good rates for signature. However, the same rules apply, the ico need to hit softcap in order to pay out).
