Don't wait the crash or the correction to buy, most of my friends keep on waiting the price to go down, but the price never go down and they never invested in Bitcoin and in the end they regret about it, so if you got spare money go and buy now, no need to wait the price to go down
Investing in bitcoin is a risk, people need to understand that, so all of those waiting for the price to go down are not understanding bitcoin at all, if you want to make money with bitcoin you need to invest whenever you have some spare money to do so, that way your bitcoin holdings are going to keep growing and in the long term your profits are going to dwarf your costs.
Spare money does not happen. The money goes to us with great difficulty. No one wants to lose them. But I think that buying bitcoins now possible and necessary. it will never be below 9000 even at the dump. By the end of this year and next year, bitcoin will still grow. All who are waiting for lower prices to buy coins will be to buy them at 13000 dollars.
