Actually this is a hard situation for gamblers whom do really make use of bitcoin because they would really be needing to deal with the fees.
As someone who gambles with small amounts it's not that hard because there's a few sites out there that charges little to no fees on withdrawals and if deposit confirmation is an issue you could switch to another casino. I might've said this before but once you've find your go to gambling site it eventually becomes less of a problem since this isn't the first time we've experienced the fee spikes the worst case they'd probably last a few weeks up to a month. Imo it only becomes an issue when the casinos you're playing on starts upping the fees and doesn't have an option for delayed or batched withdrawals.
I also prefer to gamble more but with smaller amounts. My favourite strategy is still martingale based so always start very little with my bets. The fees can be annoying but only if we deposit and withdraw too many times. If we take a long term approach than we can try and avoid paying too many fees. For me the bigger problem with gambling with bitcoins is the price. After the recent drop in bitcoin price I thought that bitcoins wouldn't rally again anytime soon so I started to gamble with BTC again. And now BTC is back to 60,000 USD almost, I wish I had taken fiat money instead.
