After what happened to the litecoin halving this year, I Don't expect too much from bitcoin.
In fact, many people still expect about the bullrun after Bitcoin halving next year although previously, LTC halving is not as good as what we expected. However, in my opinion, BTC and LTC are quite different. BTC, most people trust this coin to pump again likely in 2017, or even more, higher.
The next bull run will come unexpectedly all you need to do is stay focused.
I also think so, I do not put my high expectations to meet bullrun in 2020. Does 2020 become the starting year for bullrun? I mean that the bullrun may not be in 2020, but a year after it. For, 2020 may be the year for market recovery again?
