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. 
Crypto bullrun have already started a while ago, I think around a month now since bitcoin start breaking it's 9k resistance, this will bring good value tomorrow because this time it's not just Bitcoin doing all the bullying, DeFi projects are here too
