I think being excited for crypto is justifiable if we are talking about established coins, because the technology is superior, and one way or another certain projects will find success.

But, the amount of projects that end up failing will be huge obviously. It is impossible for every crypto to succeed in the long term. We don't even know if steem will be alive in 2020... although I certainly think it will be alive and with a much higher price than today.

You said this

But what we CAN do, is slowly change it

And that is exactly what I think crypto can do. I remember on a family meeting back in december I was trying to explain the concept of crypto, and one person say that "it was impossible to replace the banks"

Just like that... and of course, if you suddenly start thinking about replacing the banks or the complete financial system it sounds impossible, but this is not about changing everything in a couple of days, I see crypto as an alternative, an opportunity for people to not only make transactions but to also earn a living without necessarily participating in the traditional system. With both options coexisting.

Whatever happens next is difficult to say, but crypto should be seen just like that, as a cool and modern alternative, highly risky of course.
