There will always be people trying to get the loot of $100. That can be a lot of money for some, and if they are also able to do it with multiple accounts, then it is a nice snack. The Duelbits team will probably look into this thoroughly and easily catch cheaters and intervene if necessary.
Then can try but they will eventually be caught, Duelbits has maintained its status as one of the trusted gambling sites in the industry and they will not allow cheaters, as long as you are playing it cleanly and follow the TOS on Duelbits you will not encounter any issue it also applies on other trusted gambling site, a big gambling site like Duelbits will always play fair to all their players so players should do the same.
