I do not agree with that type of logic, if you are not going to win with one account, you are not going to win with 1000 account neither. You could get lucky for a while and all but you are not going to suddenly start winning a huge amount of money just because you have multiple accounts, it will always be the same result. Instead of having 1 account crash with one bad streak, you are going to have 1000 accounts all distributed with same deposit, and one by one they are going to end up losing all of your money anyway.

I would have to agree that this will probably take longer for you to crash and have no money, because 1 account is quicker to gamble then 1000 accounts, but it is still the same game and same logic and still has a house edge so I do not see any changes in the long term.
