No need to dwell with the past opportunities but instead moving forward and try to see if you can take advantage of the current market, the value of those assets are still cheap compared to their last time high, there's always a good chance that those assets can rise high once it was added to binance, you can buy and hold till the value reached your target peak.
Do your DYOR and the rest will be passive for your investment. Keep on track of all the progress and activities. It gives a lot of positive vibes while holding your assets.
Don't expect gambling coins to be listed on Binance, so far only one gambling token has reached trades on binance and besides that the average gambling coin trading volume is very low, so it will be difficult to meet the listing criteria requirements for submission to the Binance exchange, but if for passive income from analysis of project progress then it's your own consideration but don't speculate too much before you are disappointed with the decision.
I think there is a restriction to these casino tokens because even the DEX won't list them. I just couldn't find a regulation news about it because its a hand off for exchanges. If it were just listed on Binance and the casino is also popular, its going to be an opportunity for investors. It seem a win-win, casino is a cash cow.
By the way, there is a scam accusation to OWL games. Not really them but evidence shows they are sister company of SandBoxCasino.io.
