If Internet takes 60 years to flourish. I don't see why we should be skeptical about this new/infant tech which not even have 10 years history, which only started in 2009.
Sit tight, and keep a look out for the good + legit + potential cryptos to get involved in or even invest in. There's no overnight success in this world.
You made a great example with the internet and that includes every other new technological innovations, as things don't just happen overnight. I am even surprised at the way the crypto space has grown over the years so far, compared to the internet.
