Bitcoin dropping to $10,000 by 2023 is possibly but I wouldn't bet on it, too much support seems in place for it to go this low. Sounds like more FUD by institutions to increase their holdings by shaking down and out weak hands and panic sellers.
If the price drops to $10,000, it will be a blessing for those of us who want to have more bitcoins because we can buy them at such a low price that we are just waiting for the price to rise again. The important thing is, if that moment really comes, you must prepare your money to buy it so you don't miss buying it at a low price. But if it did arrive, many people would panic because they weren't prepared for the price drop.
And also sure, this time will be the best time for some companies that will start to add Bitcoin to their balance sheet but on the other side, there will be some companies that will have a tough situation because some of their entries or price of Bitcoin they bought will be the underwater situation.
