It often reduces its value a lot.
Bitcoin doesn't reduce in value as you have said Bitcoin is the most valuable asset to invest on what it does is that it only go dip and that doesn't mean it has last it value for that is just the nature of Bitcoin it is a volatile asset when it dip it also increase it is shitcoins that loses value because they are pump and dump coin, there are points Bitcoin can't drop again so change that mindset that bitcoin is not valuable when it is dipping the dip of bitcoin is an opportunity to accumulate more Bitcoin.
Bitcoin price rush should be seen as a correction I think the current decline is a correction. Of course I agree with you that Bitcoin is a valuable asset but in real assets like gold is also valuable. While the correction continues more Bitcoin should be purchased. I am saying with very little knowledge about Bitcoin that it is worth buying Bitcoin at any price. Try and buy as much as you can before you reach the top. The decision to buy Bitcoin in any price trend through Dollar Cost Averaging or DCA method will be very profitable for an investor in the future. An investor can continue to buy Bitcoin through this method based on their income for financially weak or middle-income people. Bitcoin is a volatile asset and by increasing the holding of this volatile asset through regular purchases it can be very profitable.
