When do my investment and purchase 

When do my investment and purchase price get confirmed?  Investments and prices are not final until after payment is ​confirmed​.    CoinList shows you estimated filecoin amounts at current price​for​ ​convenience​ ​only. After payment is received                             (which can take several seconds for USD payments via pre-funded AngelList accounts or up to 60-120 minutes for                                     certain crypto currencies), the exchange rate and filecoin amounts are confirmed. ​As​ ​investments​ ​confirm                         sequentially,​ ​each​ ​investment​ ​raises​ ​the​ ​price​ ​for​ ​all​ ​investments​ ​following​ ​it​. Let’s say a payment is             initiated at price X and takes 30 minutes toconfirm.Duringthattime,anyinflightpaymentsthatgetconfirmedwill                                         increase price to X + Y.
