Exbet looks promising and has some pros, but in my opinion 1% (even 0%) comission isn't enough to attract a lot of customers, especially after we consider in-play BACK/LAY spreads, liquidity and volume matched. Few things really MUST be added/implemented in Exbet in order to compete with top BTCsportsbooks (like Sporstbet.io, Cloudbet, Betcoin.ag) and Betfair white-labels (Orbit, SKYexchange, Mountbet, Satfair) and surpass them.

1) The main thing is the ability to make deposits/withdrawals via USDT TRC-20 and bet in USDT directly.
Many players don't like having their balances in volatile Bitcoin which price goes up and down every day/month. Why on Binance and Kraken almost all cryptos are trading against USDT? Because people want to cover their trading results and have balances in something stable.
Also Betfair offer betting in multiple STABLE fiat currencies.
The betting option in multiple cryptocurrencies will attract more players.
But if we stuck to just 1 currency, then it definitely should be stable USDT, not volatile BTC.
Also USDT TRC-20 transfer costs around 1$ regardless of the amount. Compare it to BTC transactions...

2) The liquidity issue. All independent betting exchanges (not white-labels under Betfair's umbrella) have this problem. Low figures of matched volume also affect and discourage people from betting/trading on Exbet because players understand that after in-play bet will be placed then marketmakers might just remove their offers thus they will unable to cover their positions or cover on much bigger spreads.
The solution is to combine exchange and sportbook service.
I mean look at SKYexchange.com cricket markets. They offer exchange odds and sportsbook odds at the same time. On both offers spreads are tight, liquidity is decent (bet limit on sportsbook). That's what players want to see. I believe Betradar (Sportradar) is the company who provide sportsbook odds for them.
For now, SKYexchange isn't perfect betting site since they have limited number of payment methods, KYC and don't work with crypto, but they built in their platform something really useful and innovate.


Hope some of this will be on Exbet too.
There are really no company in the industry which has all-in-one (great reputation, accepting players from different range of countries, not restricting players, easy or no KYC, USDT betting, exchange and sportsbook with good spreads and liquidity, API tools, livestream of events) and Exbet might become the first one, might become more attractive to players and grow.
