I hope they wont postpone their ICO to any further dates if the situation with crypto doesn't get better yet. Who know, maybe 2019 will be the last years for ICOs as we know it.
It could be. If security tokens become a hit then nobody wants to invest in utility tokens anymore.
Still depend from what is the utility, if they would be accepted in this case to pay for a visit of a doctor, people would use them. Beside that in here seems to be clear how they will fit in the platform economy.
if the utility tokens are useful and popular then people will invest either way.
