Double your or lose everything I guess is the right term lol. 5$ bet to hunt x20 on crash is very hard especially if you only have 20 bets count to have an ROI for this challenge. The daily challenge is getting insane everyday and only whales can benefits on it unless you are regular crash player that betting 5$ regularly.
The last time I play crash is on Bustabit. I remember that x20 is rare already. Players that will participate on this challenge should prepare for possible huge loss because the target is a specific win and not a wager so there's no guarantee that it can be hut using few bets or certain amount of bets.

Players can use some different strategies to hunt the 20x, it can be by flat betting or martingale starting with $1. I do not think that 20x is hard to hunt, it is all about luck. Someone may even hit it in the very first few bets if he is lucky enough but of course someone may not even hit after 50-100 bets when bad luck comes. Obviously, someone need to prepare and set a limit if he wants to hunt and complete the challenge. My suggestion is that do not spend more than the reward.
On the given requirement, it is a bit overkill if we use martingale, and the requirement is at least $5 so we cannot start with a $1 bet. As a player that has limited fund, $5 is a bit too much for me, so I guess I'm gonna pass on this one no matter how good the offer is.
I left most of the gift boxes because they all required me to wager a large amount of money after I saw the contents.
I'd rather play small than chase the rewards on offer, but I was lucky enough to get 30 FS from Duelbits, which will be given out later.
But after I saw the gift box today, I decided to try it later because using $5 to bet on Crash is fine.
Hopefully I can get the prize out of that box that says get $100
Good luck to your plan, I hope all goes well and you are able to hit the goal and earn the $100. I also play small, actually I always wager at minimum bet so prolong my gambling session. That $5 can give me 50 spins on a $0.1 minimum slot game and most of the time I hit free spin on Tome of Madness and be able to transition to slots that has higher minimum bet limit.
