This is good of you to learn before getting into the trading. Acquiring more and more knowledge will make you a successful trader. But you also need some practice – theory often differs from the real-life situations on the market. I believe that the choice of a suitable trading platform is a part of successful trading. CEX would be an ideal option, especially for beginners. You can easily buy bitcoin with fiat there (https://cex.io/btc-eur), as well as other major cryptocurrencies. Wire transfer as a payment method is free of charge. I consider it to be the most convenient exchange for trading.
