With what happens to bitcoin a few days ago, I think $47k is not a good time to invest because the price can go down to $44k-$45k, so what you need to do is trying to buy bitcoin at those prices. If you can buy at that range price, I think you can sell it back at $46k-$47k and take profit from bitcoin. That moment will happen many times, so you don't have just to buy and hold, but you have the opportunity to buy and sell and hold for some amount and make a profit. But the price can drop below $44k as no one will know for sure about that.
