I don't think Exscudo is a failed project, they just haven't thought about the community,
does here have a link to Github Exscudo? if they are active on Github I think it is appropriate to have EON
But have they successed their goal? For example they promised to provide crypto ATM and crypto cards... so after few years of "development" where are they?
Do you know the Channel App made by Exscudo? If not please go to this link:
https://channels.chat/ Maybe if you see that channel app it will make you think to buy some EON now.
