If you are experienced in the navigating in the stock market I would say Coinbase is not for you. It will most likely be your first point of entry to purchasing crypto currencies, but you will soon find out that the fees are way too steep! Paying 3,99% fees and not having the option to control the price you pay will soon get you hangovers. https://support.coinbase.com/customer/portal/articles/2109597-buy-sell-bank-transfer-fees

I recommend SEPA to kraken.com (if you live in EU). I know kraken.com is a horrible exchange but as a point of entry to get FIAT into the market it is okay. Then transfer ETH/LTC or BTC to Binance or some other reputable exchange
