This is actually one of the reasons why I’ve completely stopped gambling as of recently, from playing games like dice to betting on eSports matches. I do have some fiat accounts with cash on them, so I’m going to temporarily bet on my fiat accounts while this little battle boils over. I haven’t moved a penny of my coins since the big drop yesterday was messing with the exchange prices sites like Bitrefill were charging for Amazon Giftcards as well; it’s unfortunate that the BCH battle’s affecting BTC in this manner, but I’m sure it’ll be over in a minute.
True, with the current volatility of the market as it is now, the best bet is just to be using fiat.
At least, with your winnings, if you manage to anyway, you can easily buy back into bitcoin eventually until the coasts clear.
Certainly as things are going now, there is a huge possibility we might get to see bitcoin go down the more in the short term towards the end of the month, but all the same, it is the market, and we all know how volatile it can be, which is why I agree as well with the OP, that at this point in time, it is best to even stay clear of gambling with bitcoin.
