I think you should wait for the bitcoin value to go down a bit and then start investing in bitcoin because that may really help you get some bitcoin to invest in it more so you can buy the things you want.
Bitcoin price is unpredictable we do not know what will happen with the value of Bitcoin in the next day. But if you see the current popularity of Bitcoin that has reached a new value, it is difficult to predict when Bitcoin will go down. Better to invest now because Bitcoin's value will go up.
