Going by history, BNB was launched in July 2017 around $0.11 but reached an ATH of $686.31 on May 10, 2021 just after three years. Currently trading above $550, BNB has established itself as one of the top asset class to hold for many people coming into the crypto space. Can only imagine what to expect in this coming bullrun.
The truth of the fact is that BNB was able to rise and become successful today due to the influence of it's native exchange Binance, which was known back then and still now to have the highest Bitcoin/crypto trading volume, and a pioneer exchange token if not the first if I'm not mistaken.
So in regards to second question about what price to expect this bull-run, I will roughly say if only Bitcoin can hit $100k just as predicted by many, then let's expect to see BNB hit $800
Although there are other exchange tokens that are also performing well but this three looks the best investment option looking at their respective ecosystem growth hence I feel they are good investment option with growth potential but I will like to hear your opinions.
The potentiality of an exchange token is dependent on how large it's exchange community is, because the larger and bigger an exchange is, the more higher it's token likely to become very successful in the market after launching. Hence, always note that investment is a risk, and only those who are willing to bear the risk should always give it a try.
