As of this late, I notice that the fee is not anymore that high compared to the last week when there's a little panic due to bitcoin's dump or the market dump. per
https://mempool.space/, this is the estimated fee now.
Low priority
54 sat/vB ($4.30)
Medium priority
68 sat/vB ($5.42)
High priority
83 sat/vB ($6.61)
However, that would drop from time to time so probably a $3 fee is still fine and will be confirm in less than 24 hours.
Those who are dedicated to using Bitcoin in their gambling will wait for the right time to deposit, but for those who had an schedule time to gamble will not do that, they will opt to use other currency, with Bitcoin's fee going up and down, many gambling sites have install other popular altcoin's as choice, the gambling casinos who can only offer Bitcoin and Ethereum will have a hard time attracting many players to play in their site.
