Do you homework, try to ignore the white noise and look at alternatives such as Ethereum, Ripple and Iota (among others).
I don't do homework, I do common sense. Here's a few facts about cryptocurrencies :
- The moment the remaining wire-transfer and credit card connections between cryptocurrencies and real currencies are removed by first world nations, cryptocurrencies are dead. It can not sustain itself on face to face currency exchange and wire transfer in off shore nations (who would be quickly be brought to heel, or be themselves cut off from international wire transfers).
- There are no legal use cases for cryptocurrencies which couldn't be more efficiently served by a centralized entity, if it wasn't for balkanized financial regulations and their overhead. Yes cryptocurrencies "avoid" those regulations, but they can do that only as long as the first world abides it (see above). They provide nothing E-Gold didn't, with the same criminal consequences, just this time without a central party to sue into oblivion. Just like E-Gold, governments will get fed up with it at some point.
Cryptocurrency is coasting on a phantom of respectability created by the lies of people to get rich, among which many highly educated people. You might get rich by people believing those lies but you shouldn't believe them yourself. Go into it with both eyes open.
