Hopefully implementation of lightening is as good as they say it'll be. Right now bitcoin's price doesn't justify the amount of transactions it's able to handle. I saw an interesting chart on reddit not too long ago, which tracks the price growth of Bitcoin and Ethereum with their respective number of transactions processed. Bitcoin dropped off a while ago in growing with it's transaction speed, hopefully it'll pickup. In the meanwhile, I'm very hopeful for Ethereum, though increased scaling with plasma and sharding will take a while.
