I will tell you to keep the 2 BNB for long term investment and i know that if the BNB stay till next six years holding it multiple for you and you will have on regrettably profit because investing on this shit coins that you don't know the project well will make you to feel troubled but leaving the one you already have will make you not to reason the falling and increasing of any coin
I even bought more BNB because the current price is discounting it at a low price, I guess if there is already an investment in BNB then there is no need to convert it to another coin, unless you have other funds to add to the investment, so keep hold of BNB until the profit goal it can be achieved.
