Buy at least 10% litecoin.  There is enough room in this game for more players.  Hedging is most often smart.  People who use btc as currency don't like wild rides as much as all of the pure speculators.  When litecoin starts being accepted, it will also explode. 

Everyone talking down litecoin - rewind 2 years ago and just replace your words with bitcoin.  Thats what they said about btc, thats what they say now about ltc, that is what everyone will think about every next big thing.  It may never take off, but hedging makes for an overall better investment.

 I will abandon coinbase at my first opportunity, but right now their instant purchases win the day.  That is risky for them to allow with chargeback and stop-payments.
