Some casinos (at least some local ones) don't let's you to take different odds from one game. For example I mean let's take FC Barcelona - Arsenal <---- Bet on 1, number of goals over 2.5, number of corners over 9.5, number of cards, all of these from one game.
Also cashout will be great, function of editing bets before game starts (to add or remove game). Also promotions like 100% cashback if 1 bet loses from 5 one, 150% cashback if one loses from 6 and something similar.
In fiat betting, you can never make parlay (multiples) bets on markets in the same match, like your example.
This is due to what is called "related contingencies" - which means that the odds on the second (third. fourth, fifth) bet in your parlay would have been different if you would have known the result of the first bet.
So I don't think it is reasonable to expect this functionality in BTC sportsbooks.... do you know if it is offered anywhere? I would be surprised.
(*UNLESS* the sportsbook modifies the odds of same-match bets put in a parlay... but that would be very complicated.. and not a lot of demand for it..?)
Even in parlay games they usually do not allow you to bet on the same game. For example, you can play on 3 different matches and parlay them together and have 1 bet on all three and that is parlay for you, that you can do everywhere. However, if you wanted to do parlay with one game but different 3 bets they do not allow you to do that. That is like that in almost all sportsbooks all around the world. That is a big miss but also that is a way of sportbook keeping itself safe.
When Barcelona plays with a team that they are bound to win it is usually easy to predict that Barcelona will win, Barcelona will score a lot, Barcelona will do bla bla bla and so forth, which means if they allow you just one bet like Barcelona will win they are giving you basically free money most of the time but if they allow you to bet on other stuff as well that "free money" is getting really high.
