I am pretty sure that all the wait for the bitcoin halving craze wasn't for today, that can't happen this quickly, I know it has been a few months and people have been expecting a rise because of that reason, however that is not logical to think like that because halving is not something that changes prices instantly, it is a long term thing. Think of it like lower inflation, it is a good thing, with lower inflation your money keeps its value longer, but it is not one time quick change, it is a long term years thing.
Bitcoin had halving and miners makes less bitcoin which means they get to sell less bitcoin and that means there is less money sold and that will change over time. Obviously it may take long time, maybe it will take another whole year? Who knows.
If you analysis the bitcoin and altcoin market is moving good after the bitcoin halving. There will be moments when there will be some correction but overall the market trend is positive. By the end of 2021, we shall be see all time high of both bitcoins and altcoins.
I see that since this year, the bitcoin and altcoin market slowly making the right movements, and it prove from the increasing of the bitcoin and altcoin price. No matter if the price is up and down, and sometimes down deeper, but the price will be back to the high price. Perhaps, what you say will become true at the end of the next year, but I hope that bitcoin will pass more than $15k by the end of this year. If that can happen, we might get another best moment to sell bitcoin at the new ATH after waiting for a long time.
