The question here is whether you have an investment plan, starting with an emergency cash fund, either at home or in the bank, but easily accessible. Then, if the purchases you make are made with money that you are not going to need, I would say that for at least two years, which is when it is assumed, and I say assumed, that we will be around the peak of the next cycle. But what happened in previous cycles does not have to be repeated, although it is most likely that you will, so the most important thing is that the money you can put in bitcoin you do not need ideally for the next 4 years at least, to withstand the volatility. By buying regularly and doing HODL, you will have a better future.
