I think I've been playing for 5 days now and I'm currently at level 4. I also managed to win 6.66 USDT on the wheel, but it’s not withdrawable at the moment. Hopefully, they will make it withdrawable soon. I use the maximum spins every day, and in these 5 days of spinning the wheel, I only won USDT (6.66) once. Most of the time, I get the in-game token. I hope this airdrop doesn't take too long. They should follow $DOGS for example, which distributed their airdrop after about a month. I only have almost 50K in game token right now, thats because I max limit the spin wheel.
I'm trying to accumulate as many in-game tokens as possible. I assume that wheeling is not the only activity where they should be spent. It is quite possible that under the terms of airdrop the number of in-game tokens will be taken into account and it may turn out that the more in-game tokens there are, the more $BC tokens will be provided by the organizers. For example, the airdrop from Notcoin took place according to this scheme. As for the timing of the event, there is no information or even hints so far.
Yeah, accumulate as many in-game tokens as you can because it is a major factor in determining how many airdrop tokens you will earn. However, it will not the final amount of tokens you'll receive. I think they will rely on the "history revenue". You can find the "history revenue" upper right in game. So, I guess we should spend the in-game tokens while we can since I don't think it will matters how many in-game tokens we have at the moment. But it's still up to you if you don't want to spend them. That's the only possible scenario I see happening about in game tokens.
