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 just some of the stat that contributes to where we are right now, I believe we are already in bull run although I still see some coins having a hard time with their price to pick up, things are getting better we are all hoping in this community that it will keep on like this after the pandemic where the market will perform much better.Plus there is a lot more activity which means back in the day there was 100 bought and 90 sold, nowadays it is 300 bought and 290 sold, the difference is still 10 but at the end of the day the trading is a whole lot of different from the 2017 peak times, there are tons of more money involved and since there is more money involved I just assume that there is more people involved as well but that is not something I can prove.
