Dont know about coinbase. I started buying 'dash' paying on paypal via 'wesellcrypto' but I lost interest in dash, they had already gone up heaps before I got involved & wesellcrypto kept running out, so sent my dash to poloneix & started trading and added bitcoin through btcmarkets as I could afford. Done really well so far.
Also I love the market being 24/7....I wake up at 3/4am sometimes & check market, occasionaly trade......truly is a diferent world.
