I was in a hurry to sell the bnb at $245 and currently the bnb is as low as $280, I can only suggest you buy below $245 if the price drops drastically. We are facing a bear market and the market price below $30k is approaching.
in the actual correction process, you can get it gradually. this is just to anticipate the market when the price suddenly improves then you will not be left behind. that's because we won't know where the bottom of a trend dump is.
but buy it now hold it for 2 years in the future I don't think there will be any harm. this is something good in the future. we will not regret at all buying BNB.
