QUESTION A)
What is the best way to spend your first crypto?

I would look for a way to make more money with it. Why? Because crypto market is way more volatile than stock market and so, you can see some overreaction on the market from a far, and you already know what the market will look like in few days or so... Otherwise you have some financial indicators to give you a clue. So I recommend to play a little. Little bit of stacking and little bit of trading. And also try to buy something cheap. Just so you will get a grip.

QUESTION B)
Who are the crypto industry leaders in your view and why?

I can only name a few, I know. And those are Blockchangers, Soulab, Unicsoft, and the old company Altoros. They deliver smart contract solutions, build dapps, consolidate... Why? Basicly those companies are massively bringing blockchain technology to every company (one way or the other). Companies are bringing this technology to their workers... see where I'm going with this?

QUESTION C)
How is the crypto world going to look like in 5 years and what are the most important initiatives today that will take us there?

I guess corporations and big banks will try to take over most users with their centralised systems. But I think that's too late, because most people who already use cryptocurrencies daily, will not go into the system where someone can just block your acccount. I think crypto world will be a lot more ...let's say useful for masses and easier to use. Cryptocurrencies will be many times trading between friends instead of central bank currencies. Because by that time, people will know better how to use them further. And most important initiatives today are to make usefulness outside of web in real life...happen. I am talking about local shops, all kind of services including tourism....where you can pay with your crypto if you want. I am talking about stacking your cryptocurrency on you favourite hairdresser account, so you will always have 20% off... did I go too far? :)
