Virtual currency I envisioned is ALVA - Alternative Value. Alva is LETS (local exchange trading system). LETS helps people exchange their goods and services using simple credit clearing mechanism, so actually people exchange goods/services for goods/services without need of official money, where transactions are written down in centralized database like blockchain. Alva is not convertible to money officially, only between its users. Value of Alva is pegged to RSD (serbian dinar) only in beginning, so after it becomes market regulated by participants. Alva is like electronic bank, e bay and social network in one.
Brixton pound is also vitrual currency pegged to fiat money, So Nantes to euro
In its final stage of development it supposed to have 1 bilion TAL (vote shares). Vote shares are good because they eliminate 1person =1vote democratic system and instead use corporatocratic voting.
If we can say Nu is 3rd generation cryptocurrency, i suppose ALVA/TAL would be 5th gen, with many advantages ( i will gladly deeply elaborate this in future) - But now we are in first stage, we had test platform last year and i hope we will finish final version with beginning of next month. It will be on Serbian but we will translate it in English as soon as possible, as it also has global potential.
I think that would be best option for Nu to try more local approach to get acceptance and marketing other than classic internet marketing. Issuing Nubits have great similarities with central banking and could breakthrough if somehow focus on peoples existential needs (social, healthcare, enviroment), so i will try my best in these areas.
