no, who promised, Bitcoin never uttered false promises, human beings themselves were 'too ambitious to say something after (Halving) happened'.

What you need to know is: you must understand from the Bitcoin mining costs incurred by Bitcoin miners, if production costs are greater than the current price of bitcoin, miners can automatically out of business, (LOSS) with the simplest reason they actually sell their reserve Bitcoin for production costs which must be spent every day/month and year.

Example: if we compare the production cost to $ 12 thousand, at least the price of Bitcoin on the market will be $ 24 thousand, this can make miners think positively.

So, what you need to understand again is: after the end of Halving that occurred in May yesterday, the price of Bitcoin is still in the position of $10,000, it's only natural, on the contrary Bitcoin is currently priced at $9,300, in my opinion you don't complain and you can still buy and invest.
