We have spent 2 years of test marketing in Asian countries to research people's awareness and interest in this industry.
What we figured, is that there are different types of people who are interested:
1. people seeking for investment opportunity
2. people who really sees future in the industry
3. people who are really in need (for low transaction fees etc.)

The first step is to understand why you are curious or interested in this industry isn't it?
If for investment, then of course you should seek for whatever tokens that have potential in growing.
But then it is also important to learn how economy circulates in this world.
Although Bitcoin for example is decentralized, it is important to know who owns them the most or who are in power at this stage.
XRP is operated by Ripple, which means of course they are the controller of the game.

As crypto and blockchain industry is well paid attention to now, many of them seems to be making great price increase, but we should all know that in order to be really widely spread (create larger demand), the controllers have to release more, which will first result in fall of the price. But then after overcoming that, there will be another and even bigger chances again, because that will be the time when the whole world admits crypto and our concept of money will change.

Hopefully this can be some help to you for further researching : )
