In online poker, there's a theory that players suffer through a cash out curse when they go to remove money from their account. Going further, poker sites supposedly punish players who cash out by giving them worse cards. This same belief exists in online blackjack where internet casinos are accused of giving blackjack players bad cards after they take their money out. 

One basis for this curse is that some blackjack players believe casinos want to discourage their players from withdrawing money so it's kept in these accounts. Fortunately, anybody who knows a lot about online casinos realizes that the casinos would never get away with instituting punishments against players who withdraw their money.

Online casinos adhere to strict regulations by their licensing jurisdiction, and any company that was caught doing something this wrong would immediately be punished. Furthermore, blackjack hands are decided by a random number generator online, which is exactly as it sounds - "random." So if you're worried about suffering through a huge losing streak any time you cash out, there's nothing to fret about.

Sure there will be still times when you go on a bad streak after cashing your money out of an online casino. But just like in land-based casinos, players go through both good and rough streaks. So you could just be suffering through a bad time where the hands aren't going your way following a cash out.

In any case, remember not to let these bad streaks affect your blackjack strategy. After all, if you stick to solid blackjack strategy, you can lower the house edge to 0.5%, which gives you a very good chance to win money!
