According to Binance CEO - CZ, activity on Binance exchange is higher than in December 2017. According to PlanB that created stock-to-flow model, the bull run is here, his claim is based on the value of RSI that is currently on 64 points. And the last positive claim comes from Goldstein that said that Bitcoin already has value more than $100,000 because there are statistically more people that will hold BTC to this level. 
This is pleasant to here. I think most of us have been expecting this. The usual expectations from history of bull run is that, after the halving have taken place, either that year of halving or following year comes the bull run, and that was what happens in 2017. Likewise, we are probably expecting bull run towards the end of this year or 2021.
