At @Scoresby's request, this is a summary of the different places to engage in sports betting degeneracy with your bitcoin.

Starting with ~Stacker_Sports' favorite, Predyx is a lightning only prediction market, where you can buy and sell shares directly with your own wallet. Despite still being in beta, they're already the most fun betting site and they offer better odds (i.e. lower spreads) than the regular sportsbooks discussed below. We also have access to one of the founders, @mega_dreamer, and devs, @emre, right here on Stacker News. They also took over ~oracle from @ek. These are our people.

The focus is more on longer term and more noteworthy outcomes (not exclusively sports), so they don't have the full offerings of parlays and moneylines and so forth that you might be looking for. However, the real-time odds adjustments as other participants buy and sell presents great opportunities to capitalize on price movements.

BetPlay is a traditional online sportsbook that allows lightning deposits and (I think) bitcoin denominated bets. They also accept various shitcoins, including fiat, and report all values in fiat terms, which is frustrating when you're trying to make a specific sats valued bet. The latter is useful for arbitraging odds mismatches with Predyx or Ember.

Also, my favorite thing about BetPlay is that you can watch live feeds of just about every sporting event in the whole world. It's amazing.

This one is fun, but comes with a major caveat emptor. Ember is a mobile app (referral code MNGKHFGBTRM) that streams sats to you at a fairly slow rate when you login. With those sats you can bet on upcoming sportsball matches from several different sports. While games are in progress, keep track of the odds over at BetPlay, just in case there are opportunities for arbitrage that you want to take advantage of.

The warning is that we've experienced inexplicable losses of sats from our balances and had difficulty withdrawing, so I strongly recommend against buying sats from them to increase your balance. Just play with the free sats and have some fun microbetting. I think Ember is supposed to have lightning withdrawals, but I have yet to be eligible for a withdrawal.

OGs remember freebitcoin as a faucet that used to give away ludicrous amounts of bitcoin, but they offer a seemingly random smattering of sports betting options too. The biggest downsides are being on-chain only (with a withdrawal fee) and the limited offerings.

What I most enjoy about Freebitcoin is that they have an unusual betting model and actually offer better-than-fair odds to early bettors. The rub is that when you place an early wager you have no idea what the odds will end up being, because it's a betting pool that divvies up the pot proportionally to those who picked the winner (usually). They have gotten outcomes wrong and never corrected their mistake.

I've described my approach thoroughly in RBOA: Risk Balanced Odds Arbitrage, but it's basically to bet early on all the outcomes and make a small not-quite-guaranteed return.

You can also check the odds right before a match begins to take advantage of mismatches with either BetPlay or Predyx.

Nitro Betting is very similar to BetPlay, but is on-chain. My cursory comparisons of odds on the two sites indicate that Nitro might have slightly lower spreads than BetPlay. However, I don't know if that compensates for on-chain fees for deposits. They also have higher minimum bets and a minimum withdrawal threshold. They do, however, express bets in bitcoin terms (rather than fiat), which is nice.

What are your favorites, stackers?

Are there any I missed?
