It's good To read about golem I'm holding 100 gnt until 2020
You are doing right by holding at least 100 GNT by 2020 because actually that is the year when blockchain will be deployed widely worldwide and if you look carefully almost every startup has target to get their goals before 2020. I like your idea and long term planning these will be worth a lot till then.
To Be Honest I think blockchain technology is really only getting start
in relation to acceptance, OK we see it predominantly with Ripple
where the banks are signing up to the technology, and Bosch the
automotive electronics manufacturer adopting it also.
but there is massive room for expansion and acceptance, so yes Golem
can go a long way ..... in theory.
