Tips to reach wager 3000 while losing the least

I used a streamer deposit bonus where I put 50$ and got 50$ extra, I thought the 30x wager requirement would be on the 50$ not on the whole 100$ so now I have to somehow reach 3000$ wager.

Currently I have 200$, do you have any recomendations to quickly reach 3000$ while keeping as much as possible?

(Keep in mind Stake only allows me to do 0.50 bets maximum)
