With all due respect, if high volatility, or devs missing deadlines causes you to lose trust I don't think crypto is really for you.
The Gulden team have given regular updates on development and explained why things are taking longer than originally planned. The upcoming update is huge. Would you prefer them to release it early with bugs? Would that make you trust them more?
It's not the Gulden team's job to do marketing. Marketing in crypto only creates hype which creates more volatility. If they were aggressively marketing and creating hype that created more volatility would you trust them more?
What the Gulden team care most about is having the best product that gives the best experience to the user . They're well on the way to achieving this goal. This is why I trust them and is why you should too.
