This project looks promising but i can't seem to find it's whitepaper and do you guys plan on starting any airdrop or bounty project.
I do not speak for the company, but, to take your points in order:
Whitepapers are an ICO sort of thing. Bankera's ICO finished over two years ago (it was one of the most successful ever). You can see the current roadmap on bankera.com.
Bankera is establishing itself as an EU regulated, fully KYC/AML compliant bank. A bank for the blockchain era. Pump and dump schemes like airdrops have no place in such an environment so, no, no airdrops.
BNK tokens do, however, accrue Weekly Revenue. All BNK holders receive income proportional to their holdings every week. Over 100 WRs have been paid already.
As with most reputable projects, bounties are available for validated bug reports from software engineers.
Hope this helps, ToWS.
Why not buy a few BNKs (they're ridiculously cheap right now) and come and join us in the official chat.bankera.com. Bankera staff are on hand 24/7 to answer your questions and even the founders drop-in from time to time.
