don't rely too much on their promise, just keep up with their updates and developments. reaching top 100 is not an easy walk in the park. it will take time and they may achieve it, but not outright. it may take months or years or they may easily get in, but the sustenance of the position would be hard.
if they will keep on innovating their platform and retain the interest of their players, they can achieve such status in no time.

Well it's better we will observe developments for the next few months, btw tokens that are under the TRON contract rarely enter the top 100 market
If successful, of course BFG will be the first IMO and tokens with staking mode usually go into sleep mode investors prefer to keep tokens and volume does not increase

I think the cause of that is more so that there's (afaik) a lot less Tron projects that exist compared to ETH or BSC. The ones that do exist aren't doing terribly, like BitTorrent (#44), JUST, SUN or WIN (the latter which is a pretty big competitor to BetFury). I don't know if I'd expect Betfury to hit top 100, but I think there will be decent value attached to BFG especially if BetFury continues being able to attract large betting volumes.

They started off as a Tron casino, so I wouldn't be surprised if they stuck with Tron. I vaguely recall being able to withdraw BFG tokens at some point, but it doesn't seem to be an option anymore. I'm not 100% sure if this is real, but I think the token exists already. (update: fake). This is the real token contract.

I do like Tron chain as well. They are really pretty cheap and fast.
Just like for example, if you compare the withdrawal fee of USDT (TRC20) vs USDT (BSC/ERC20), TRC20 chain is very cheap.
So if they will continue to use Tron for BFG token, that's fine. You don't have to pay ridiculous fees transferring the token.
But let's see their final announcement once the listing is finalized.

According to a support rep, tokens are unlisted with no info on the blockchain protocol. Until further notice, as they always say.

You are right in this, but you also have to take into account that already through the auctions the Betfury team has been testing the "Offer" and the "Demand", so they may have information according to their community that it is the one that handles the tokens, of course I imagine they have made the calculations to be launched on the market in an eventual Exchange, it must also be borne in mind that this token will have a bullish future depending on the type of Exchange that is going to carry out the trade.

Everyone is waiting for Binance or a similar one, you just have to wait, also Betfury has never disappointed its community and I am sure this time it will be a pleasant surprise.

Browsing crypto media, I found an advertising article.  Previously, for some reason, they did not come across.  Everything is well stated in the article and I congratulate the devs on the promotion of the Casino in the media

Bullish future could be destroyed with a horrible start, things are that easy to get ruined in the crypto world. I believe this project has a huge future but the reality is that if we do not end up with something good in the quick first few weeks then we may never get it, we need to show people that it is a great one right at the launch so that they could continue to respect it.

If the price starts to dump a whole lot from the first moment and then people end up with nearly nothing afterwards, then I would have to say that there is a reasonable understanding that others would start to sell as well and it will be a huge crash and recovering from a huge crash is not an easy task, it will be very difficult. Long story short I would have to say that there is a good amount of chance we could end up with a bad launch and that could hurt us, we need to take care of that.
