I want to make crypto calculator to calculate prices in CZK and EUR of cryptocurrencies and calculate the price of crypto in other cryptocurrencies. I want to have current prices of cryptocurrencies (from coinmarketcap or other) and I want to add my fee to the calculator. After customer fill his request to the calculator it would take him straightly to the payment option on my webpage. So I want to drop down list with every cryptocurrency I have (almost 50). And drop down list where are sorted crypto and classic currencies (CZK, EUR). Every currency in dropdown list should have a picture next to it. The design should be modern in colours of my webpage - black, orange and white (Im adding picture).
