If you buy a bitcoin in the price of 9000$, yes it may drop, but we have clearly seen that this is what it does. It goes up and down. If you have 1 million dollars and buy 100BTC (900.000$) then the only thing you have to do is wait. Because someday it will pass that number and you will have profit. Am I wrong?
Recently, my friend wants to buy Bitcoin and Ethereum and needs my advice. However, he was a bit afraid because the price already went up high and a possibility of getting rejected by the resistance. Like I told him before, invest and trade at his own risk because this is a big emotional test for us in case the price goes the other way around.
We can be afraid sometimes, it's part of the journey. Expect the unexpected. If we think about long-term and believing in the success of Bitcoin, there's no reason for us to be afraid even if it goes down without warning.
