if i were to look into digital currencies today, where would i start? back in the day (last time i thought about it) there was only bitcoin, and only three or four exchanges i could find. is coinbase the way to go for a n00b?
things i know about cryptocurrency and the blockchain: just some words, really. and sort of what they mean, sometimes.
also is bitcoin still the thing to care about? i hear things about ethereum that sound interesting, i guess. i just don't know anything.
