The same four questions asked of all ten. Rails is how many networks the cashier offers for USDT. Floor is the cheapest deposit the cashier will take. Hold is whether a dollar deposited stays in that dollar.
What the grid shows once you read down the columns
The floor has the widest spread on the page. Cloudbet, BetFury and Razed all take a tenth of a dollar to start. Winz.io takes twenty. That's a two hundredfold difference in what the same casino market considers a reasonable minimum, and the higher rate does not include anything extra for players.
The rails column matters more than it looks. A casino with one network decides your rails for you, and if your coins live elsewhere you must pay to move them. BitStarz allows Tether on Tron alone, charging a fixed fee plus a rate to convert anything else. A casino with nine networks gives you the choice, though BetFury has pre-selected one ten times dearer than its own cheapest.
The hold column is the quiet one. Most of them let you keep your dollar. Look out for the exceptions, as a yes that says "only on Tron" or "not stated" carries a different weight to the player than a plain yes.
The regulator column splits cleanly into two tiers. Four have a Curacao Gaming Authority licence; five have an Anjouan licence on Costa Rica companies. One publishes nothing at all - that is the single biggest deduction on this page. Both formats are decoded, with the verification steps, in the licence number guide.
These ratings have been topic-adjusted. A casino is scored on how well it deals with a digital dollar. Beauty scores zero and an undisclosed licence costs a lot. That is why Mega Dice ended up last despite having some of the best cashier economics and why Razed has climbed up the ranks on the strength of one measured payout.
