But sometimes the phase will be different if you start to cashout your money on gambling site. For sure this crash affect even if your old timer because you will possibly look at the value especially when you bought yours at expensive rate. But if you mean upon gaming surely gamblers will ignore that because what mostly gamblers aim is to enjoy and try to win their games.
That's a different story now since that person badly needs to cash out.
Price volatility has nothing to do with that as we are the one who needs to adjust.
For me, bitcoin being crashed or not won't impact those gamblers since I think that's even an advantage to them as they will have more Bitcoin in return if they will purchase it by cash. Since they are playing with Bitcoin currency on the gambling site, it means more bankroll to them that they can use in the long run.
When it comes to cashing out, if it was really necessary to do, whether the trend is uptrend or downtrend, these guys will convert their Bitcoin to whatever price.
