Do you know the character or team of the Umbria project? what makes you believe in their vision and mission? I didn't get much information and when I browsed the Umbria website the information was very brief there
Online Blockchain plc - a UK-publicly listed company - is acting as Umbria’s coordinator, administrator and advisor. "Online Blockchain (LSE:OBC) has been an innovator and incubator in finance and technology for over 20 years and brings a high level of trust and credibility to Umbria."
