blockchain is here to stay that's for sure

as for the state of cryptocurrency... it depends on regulations in various countries. Some (like US) won't be very favourable and are already looking into a lot of disadvantageous regulations for utility tokens for example.

Smaller economies will likely be a lot more receptive because new tech means new talent and more advantages for their country (Switzerland, Japan).

I'm worried about illegal stuff stored on a distributed ledger that people might not know about and the regulators might come hard on in the future.
It's likely that the space will be very polarized for a while. But when some see threat, others see opportunity. Technological progress involves risk taking and blockchain has already changed the internet and it will continue to do so. Let's hope for the best!
