For fck sakes devs if you implement PoS Guldencoin will explode. You know how economical Dutch people are. If they have a safe, financially rewarding alternative for the euro and banks with their extremely low interest rates, how many Henk and Ingrids will join the Guldencoin community! Perhaps in the future a Guldencoin exchange euro/Guldencoin is a good idea if it's doable with all the licences and stuff...

For the average Henk and Ingrid crypto is complicated. Along that crypto isn't
functional for them (like they could spend it anywhere), I believe these to be the major obstacles for them in joining, despite if a good interest rate would be upon Guldencoin.
Personally, I'm not very fond of PoS coins. If/when the devs were to implement this at some point, I would rather see that happen in a later stage, when the total active Guldencoin users have grown larger.
