At first glance, this may be a weakness of the house, but if you think carefully, this is very necessary. For traditional betting, if you want to play when you run out of money, you can debit, however, these debts will definitely generate high interest so you can easily fall into debt.
As for betting at the house, if you still have money, if you don't have any money left, you must add it. If you don't deposit, the house will not let you bet. This, if you have good luck, will help you regulate your capital and have appropriate betting methods to avoid the consequences of falling into unnecessary debt.
