Hi, i have some questions regarding the presale of perk coin and investment in ICO whether the promo code "bitcointalk"is still valid to receive additional with intial investment. It seems i have only seen old posts and need to get updated. If purchasing with US dollars how does the transaction occur and how long till i can put the coins in my own possession of wallet. Will the Ledger S be used in storing coins or how is this being setup for private storage? Thanks for your help
