If the can have their own coin which is BNB then i see nothing bad in them making decision to create their own token, other exchanges too could have been on this same thing, i want to believe that binance exchange have realized the level of global recognition they have achieved already and wouldn't want to make any silly mistake or funny thing in creating what will low down their reputation to their users and the world entirely.
Yeah, Binance Labs focuses only on investment profits, while also supporting the development of promising new projects to promote the overall development of the market. Labs invests in MEME because they think it can actually generate profits for them. The MEME token has also been listed on Binance and has a trading volume of around $9M/day, which means it can bring Binance transaction fees of 0.1% ~ $9K/day, contributing to the future buyback and burning of BNB.
Memecoins have also become a culture of the crypto market: Avalanche & Arbitrum Foundations have both invested heavily in memecoins because they can drive ecosystem growth. We should also be more open-minded about this decision by Binance Labs.
