At the moment the price of BNB is $27 and I think it will be very difficult to rise above $30, so personally my opinion on BNB should be sold
Where do you get this information from? What are you lying about? Of course, in perspective, the token will indeed grow because in terms of project value and use of the token, there is much room for it, since IEO is performed using this token.
Certainly, we have no doubt that BNB will really have an outstanding value which may make it find its way to be the 3rd on the list in near future, but right now, I feel BNB is a little bit overbought and because the market does not experience much dump that much, very soon the investors who has been holding on to their coin will all reason to sell, most especially investors that invested when Binance was still $1.
The moment Binance rises to about $30, then we should really expect a very big dump that will drop the value of Binance back to $10, but the advantage of this is that other investors who also believe BNB has been overbought will grab the opportunity to also invest much in BNB market thereby leading to anther price surge of BNB.
