The word "Soon" has a broad meaning.
It maybe a week or a month or in a couple of weeks or maybe 6 months.

Regarding the bottom, I don't think that this is the bottom already. I expect Bitcoin to go as low as $30,000 but I might be wrong. With regards to rebound, it will not happen at least in the next 2-4 weeks. We are in a bear market and this will take months before we might see a upwards movement if there will. If the sentiments will change in the next months then we might see a rebound with the market.

Is it time to buy?? Hell Yeah!!!!!! If you have spare money, just buy those top coins and hold and be patient. We've seen Bitcoin went as high as $69,000 already so many are expecting that this will happen. When? We don't know but for sure Bitcoin will reach that price again.
