I created a web wallet, have questions ....
How is% accrued, is it POS or does it come from some reserve? from which fund is V-Staking credited.
on the wallet there is the possibility of exchange, as an example, I translated the BTCZ and would like to exchange for the VDL
and most importantly, how can you add a new coin to your wallet?
Hey there, so check out this infographic for a good breakdown of how V-Staking works! As far as exchanging coins on the V-App - we at first were using Changelly to allow coin conversion, however they changed up their Terms of Service and we had to discontinue using their services for the time being. We are looking for an alternatives, however, there will most likely be an in-house solution/tool for that - and other cool stuff in near future. The 2019 "Vidulum Vision" will be released to the public soon so stick around for more info!

As far as adding new coins - if the community feels strongly about adding a project to the platform and brings it up, and we also agree that it is a safe and worthwhile project, (and assuming that it meets the V-App requirements) - we will typically add support. If there is anyone against the idea, we would hold a vote! Sometimes the team will choose project we wish to support/associate/work with.
