The thing I do not like about BTC .... I have had a nice run but now must pretty much double my bet amount in BTC to match the dollar amount I normally bet.
You should be glad that this is your only BTC problem.
Most people playing for BTC keep a lot of funds in it, so they've lost a lot of money in recent days.However, I think this is only a temporary drop and soon your rates will return to the previous dollar level.
I did not mention my account lost 50% of its value since I bought in at a time of high price. However I do understand your point. My loss is minor compared to many others. I do agree that price will return with some patience.
This is the biggest plus and the biggest minus of Bitcoin - you can earn a lot on it, but you can also lose a lot.
At the moment, whether someone will benefit from Bitcoin or lose depends on patience, because sooner or later the price will start to rise.
I am also wondering how to bet in relation to the USD level and the only option I can think of is betting on Tether or USDT
