Well, if big exchanges like Binance will list RLB then it's really possible to surpass the previous ATH. Anyway, the buy and burn feature and the demand for RLB have influenced the price to increase further. We're not yet in bullish season but the price is doing good. Those who bought or received their RLB through airdropped made a significant profit if they're still holding at this time.
Nevertheless, invest if you believe it is worth to hold (just DYOR) but keep in mind that there's always a risk since we can't certainly predict what's in the future.
Binance don't usually list a token without listing fee. They can do it but if they see that token has very high trading volume and communities have high demand about it like Shiba Inu or Luna in the past.
Without very hype demand, Binance will require listing fee that is expensive so it is always challenging to decide spending big money to list a token on Binance or keep it for other more important developments of a platform. I don't know will the Rollbit team see that they need to list the token on Binance.
But why Binance, if the token can be listed on other Tier 1 exchanges, it will still be good.
After all, the usability of the RLB token is more important than where it is listed for trading. Usability makes a value of token, not centralized exchanges that are only where you trade it.
