I agree with you that bitcoin will not fall from $7500 because when the correction in the bull run market bitcoin has never fallen from 50% and currently bitcoin has touched a correction of 44%.
I think in the next 1-2 weeks bitcoin will come back at $ 10k

Hope this will come true that bitcoin will recover in one week or two.
But we can't rely out analysis to history, no history recorded before bitcoin pumped to 20k in 2017 and also no history recorded bitcoin dump in 2018. So we have to be careful and always set a stop loss
It will not happen, bitcoin is having problems surpassing 8500 dollars for each coin and there will be a great resistance to reach 10000, but why worry? If the price begins to go up then we all get gains and if the price remains at this level or it goes down then you can buy more bitcoin, regardless of what happens is a win-win situation, just remember that it takes a long time for the opportunities to appear and if you do not take it now you may need to wait for months or even a year to see another opportunity like the now we are seeing now.
Today, everything has happened against investors' minds and Bitcoin has been experiencing unexpected drops in recent hours. I don't think this coin will recover in the near term because currently everyone is sell panic and there is a possibility that Bitcoin could return to $7000 in the next few days. Now if you have money, you should buy at this price or wait for a cheaper price to invest because I'm really tired of what's happening.
Bitcoin and Altcoin are still falling so our predictions will never be accurate because this is a speculative market and they can completely manipulate.
