Let's go below 20k$
(seriously, you can't know.... but by analyzing the past and the differents psychologies of the investors and by knowing how the market is manipulated, then we can says that it's highly probable than it could return under 20k$)
You talk like if people were there to hear a "very intelligent guy" talk, in fact most people are investing to gain money not to support the blockchain, first fact. Second fact, if this famous "intelligent guy" was very intelligent he would have start supporting alternative coins not a slower crypto such as bitcoin is.
By the way the fact that bitcoin mining uses renewal energy doesn't justify the fact that we should use this energy to continue to mine this slow and old cryptocurrency that is called "bitcoin", there is far more better alternatives (not that i'm against Bitcoin, but there is a lack of developpement)
The logic is that it will not be 20k because of the high support level there, but that doesn't mean that it won't happen. The main idea is that if we are facing something that is not as great as people are imagining then the price will drop, if they come out of the meeting and say that they have decided not to work together and all that, then the price will drop that is the main idea, that is what we should be focusing on, because as long as it drops then there is nothing else we can do to try to guess if it will be 20k or not.
I say there are a lot of support levels that needs to be broken, dropping under 28k first, then dropping under 25k, then 22-23k level which has a huge support, so we have a lot of support until 20k and that means its hard with just one tweet and one bad meeting. However like I said, it is basically anything goes in crypto.
