Will we see Binance coin bubble? I guess we will see it occur, after hitting its new all all time high. There is no exponential rise that is not followed by dramatic decrease. Lessons from 2017, on Bitcoin, on altcoins, on tokens, told us everything. It is just our perspective, accepting the fact, or deny it. It is hard to predict how long Binance coin will go before it officially corrected; but when everyone say Binance around the globe, it is time to sell Binance coin, and find other coins to invest.
Exactly. Most cryptocurrencies on the market behave the same way. Whenever there's hype or FOMO, prices tend to rise towards exponential levels. When the excitement for that specific crypto ends, prices start to decline massively across the market. The same thing could happen for BNB, although it does have some utility to it, in contrast to other cryptocurrencies which are purely speculative.
Despite this, Binance Coin's success is largely determined by its underlying company (named Binance). In the event that Binance exchange fails, so will BNB leaving many investors "holding the bag" (bagholder). Still, this seems very unlikely to happen right now, as Binance continues to expand as a prominent cryptocurrency exchange. The new DEX, the BEP2 token standard, Binance Chain, and more, will truly change the crypto industry for the better.
Nonetheless, it seems that Binance Coin will become a great investment for early adopters as it continues to rise in price towards unprecedented levels. But be aware, that crypto is highly volatile, which could result in massive losses if you invest more than what you can't afford to lose. Just my opinion
