Right now the number is highly varied. Some are 600 some 1k some 6k some 8k some 10k. I could bet 10k across the board, but have not been doing so. Also, think in terms of ROI: 40 staked earning 8 is much more than 10,000 staked earning 200. Further, REL bet factors into total payout increasing overall payout within a community such that higher bets can be advantageous to a community overall. The project is still in beta and tuning parameters is ongoing. It still remains to be seen how high/low bets factor into incentivizing quality and disincentivizing bots etc.
