If you closely read the How to Play information for minesweeper, you will find that the 4BTC limit is enforced by a stop requirement.
"We only accept bets that have a profit smaller than 4 BTC (maximum win per bet), this means your game will not be allowed to uncover additional fields, if your pending win would go over this threshold."
You won't be able to play until the technically possible max multiplier, as the game reaches a win state before that, once you cross the 4BTC limit.
The 4 bitcoin max is a bit confusing. I mean it should be like not allowed but as far as I realize it is just a risk you take and you leave early in the game, normally I think 4 bitcoin should be at the end of the level and that is it, not have it on your 5th tile (or whatever that is called) and get out when you hit the max when there is still game to play, it makes you feel like you can win a lot whereas you just have to leave on the half of the game. However it is still good that it allows you to get out at that moment because I was afraid it would just stuck you there and you would have to wait for a support to come. I have never gambled that high to know what really happens but read from people who had that happen to them in other games I am not going to name so cryptogames made it into a better version of theirs."We only accept bets that have a profit smaller than 4 BTC (maximum win per bet), this means your game will not be allowed to uncover additional fields, if your pending win would go over this threshold."

I don't really see how it's confusing, to be completely honest. All other games also have these max win per bet implemented, makes sense that you could hit that mid-game with minesweeper
I wouldn't know of any other way either, as Joter mentioned.
