Minimums matter most to the people with the least to lose, which is exactly why the thresholds stacked above them deserve reading. There are usually three.
The four thresholds, from lowest to most expensive
The cashier minimum is what the deposit screen will accept. The bonus threshold is the amount a welcome offer requires and is usually higher — a 20 USDT bonus minimum on a site with a 10 USDT cashier minimum is an entirely ordinary arrangement.
The withdrawal minimum is the amount below which you cannot take money out at all, and it sometimes exceeds the deposit minimum, which strands small balances. The network fee is not a threshold but behaves like one: on an expensive network it can be a visible fraction of a 10 USDT transfer.

Why the network choice matters more at small amounts
A fee of a couple of dollars is noise on a 500 USDT deposit and is a tenth of a 20 USDT one. The cheapest common route is TRON; Ethereum at a busy hour is the expensive one. The network page lays out which is which and why.
This is the one place where choosing the route badly is more costly than choosing the operator badly. Two casinos with identical terms will deliver noticeably different value to a small depositor purely on which networks their cashier supports.
What a small deposit is actually for
Two sensible reasons: seeing whether an operator's cashier, lobby and withdrawal path work before committing anything, and keeping a session small on purpose. The first is a test; the second is a limit. Both are good uses.
A third reason — chasing a bonus with the smallest qualifying amount — is usually worse value than it looks, because wagering scales with the bonus and the small deposit buys a small bonus with the same multiple attached. The arithmetic shows it in four lines.
What separates one low minimum deposit casino from another
Not the lobby, which is bought from the same studios everywhere, and not the marketing. What differs is written down: which USDT networks the cashier credits, what the wagering base is, what the withdrawal limits say per period, and whether the verification clause names a threshold. Four documents, a few minutes each. How to read them quickly.
