I think:
- blockchain technology adoption by bank is just some word, that nobody knows what it should mean, but it is a magic formula used over and over again
- in either case nothing like that will happen by by 2020
- bitcoin is money in blockchain and has nothing to do with blockchain technology adoption by bank
- bitcoin can be adopted by banks as money or asset class, but even that will most likely not happen in 2020, because banks have stricter AML rules year by year and this is not gonna change
- bitcoin will hit higher than 50K mark, but 2020 (halving year) is a bit too soon for 50K as median estimation
- SEC or some other organ like that will place more restrictions, but bitcoin must flourish in spite of that not because it will be nursed by official institutions; if bitcoin can not make it in hostile environment then it is not good enough; no government wants bitcoin, because no government wants private money; power of states come from control of all aspects of life and money is one of the aspects. There is a saying, something like fishes will not dry out their pond.
- In few years will come a big economic and monetary crisis. Is impossible to determine where and how it will look like. I believe bitcoin as it is now is strong enough to attract the big money as safe haven.
The only certain thing is that if bitcoin survives there will be huge swings up and down.
