It seems that the main issue on crypto currencies and their spreading around the world is that many not trustworthy people are seeking their chances to pull out some cash for themselves, which crashes the main trust in this technology. Building Trust should be key issue on spreading cryptocoins. Because this is one of the most important issue all currencies have... the more trusted they are, the more value they become/have., or maybe more more truthful: the less trust, the less value in midterm a currency will have.

sadly many bigger players on the cryptocoin market did not understand that yet, or dont care about.
