I think you should wait for a moment to see the price will get down so that you can buy bitcoin at a low price. But if you can not wait for that time, you can buy bitcoin at a price now, but we don't know if the price will be increase or not, so you need to be careful. There is always a risk if you want to buy bitcoin at any price because the price will be volatile every day, so the only thing that you can do is analyze the price so you can get the right time to enter the market.
