If your plan with bitcoin is long-term, choose to buy with the idle money you have at any time, there is nothing to worry about. If your plan is short-term, take advantage of the opportunity to buy dips to wait for bitcoin's support waves. Basically, depending on the conditions and plans, I will arrange and proactively buy when bitcoin is at a price that I feel is acceptable.
It would be a shame if we chose for the short term a very rare asset like Bitcoin, the profits would definitely be less than optimal in this case. Of course, if we want to invest anywhere, of course we are ready to separate our money to buy this asset. I think buying bitcoin when the decline occurs is very good, but it is very difficult for the price we want to happen, we have to wait much longer if the price we want has been reached. Personally, of course I will buy whatever price is determined on the date I invest, of course I will keep it for the long term.
