Understanding the fundamentals, that made it for me. I started with XNO because I was desperately looking for a working micro-payment method which at the time btc was still incapable off. Then I started to understand everything better. I think it's optimal to get your hands dirty with shitcoins to actually see what's all about. Isolating yourself solely within bitcoin without any clue on what's outside will prevent you from actually understanding bitcoin itself. For instance we can't deny the fundamental role ETH has had all along, from which even BTC is feeding now.
