Nowadays many people buy dip and sell it back to the pumping hall. May take longer or less time to reap benefits. It totally depends on the investor. Because an investor will depend on how long he will hold his investment. But usually I keep the investment for a long time and it is able to get the maximum benefit, because the longer the investment period, the higher the benefit.
If you can't buy correctly then it will be your first mistake in Bitcoin, if your investment time is short. Your risk will increase so it is definitely best to hold for the long term to reduce the risk. Here the more longevity you invest in investing the lower the risk and the best approach for you. You will save the most if you buy bitcoins using the DCA method only, and if you collect bitcoins for the long term, your investment will be long.
