Well, you've got a point with those two things.  I'm not a miner so I wasn't even aware that there was another halfening happening next year, but I've always thought those get priced in way before they actually happen.

Facebook's coin might just convert a lot of folks to "real" cryptos if they can manage to launch it.  I've got some doubts as to whether the US regulators are going to let them do it--and even if it does manage to become a reality, I'm not sure how popular it's going to be.  But it certainly could put a big brand name on a cryptocurrency and get people to look into bitcoin more closely.

2020 probably is going to be a big year for bitcoin, but we'll see.  We all know how unpredictable and wild the market is, and who knows what news might come out which could influence it in another direction.  I've got my fingers crossed that it'll at least hit $20k again.  If it does that in 2020, I'll be satisfied.
