2-3 weeks ago you could have bought at that price too. And if we think that we are at almost ATH and most of the year the price has been cheaper than $59K, I don't know if while it was cheaper you were waiting for the price to go up to buy more expensive.
Although the topic is very strange but you have to admit that it is not impossible. Sometimes you come to some money and have to buy after that. Like receiving your paycheck at the end of the month, or in case of bigger amounts (like OP's 4.5
BTC) maybe it was inheritance or something sold like a house!
