When the network is congested, I don't think they will activate RBF to speed up the withdrawal process either. Has someone ever seen a bitcoin withdrawal from a gambling site when the network was congested the transaction activated RBF?
Casinos tend to overpay on the network fees, so there is no need for RBF. Their withdrawals target next block confirmations, and I have personally never had to wait for more than 1-3 blocks for my withdrawal to get its first confirmation. Gamblers are impatience. Imagine if the casino would have them wait too long how many complains there would be in the respective ANN threads of those sites?
But it is possible if you also include what altcoins can be exchanged on each of them? or it is impossible because it will probably need some space on the new column that you will add.
I will have to see how it looks first. If there is enough space, it could be added.
On this basis, another possible addition might be something like a TrustPilot rating for each site in the format: 3.8 Stars (Out of 4 votes).
...but how about including the start date for each site as well?
I have already received a few suggestions like including what altcoins are available, links to official websites, and if the casinos have an internal exchange. If I were to include ratings and how old the casinos are, I feel like there wouldn't be enough width on the table to hold all that.
A new column or a new topic? Do you think there's more information surrounding the currency exchanges of each platform? Could it be currency, exchange rate, fee if any for each currency?
A new column on the existing table in OP. It would be just a simple YES or NO so that the player knows whether or not such a service exists there. Everything else regarding the fees and requirements to use the exchange is up to the player to check.
