Nexus Entrance / Board index /Before you decide
Nexus addresses three doors, one platform behind them

Your account, balance and orders are the same through all three. Copy rather than retype, and check the signature once you are through.

An address that opens is not an address that is genuine. The check that settles it takes under a minute.

What it actually costs

Nobody writes this page because it is not persuasive. It is the one most worth reading before you start.

Time

Realistic
Setup, done properlyAn hour or two, most of it establishing a fingerprint carefully
Learning to read the placeA few hours across a week, and it is worth taking
Each orderMinutes, plus waiting that you do not control
When something goes wrongHours, spread across days, mostly waiting on responses
OngoingA few minutes every few weeks keeping saved addresses current

Money you can see

No buyer commission, which sounds like free and is not. Vendor fees are priced into listings, so you pay them either way and the difference is visibility rather than incidence. Comparing platforms on advertised buyer commission tells you very little, and comparing the price of a comparable listing tells you almost everything.

Money you do not see

Risk, which is the real price

This is where an honest accounting differs from the usual one, because these do not appear on any receipt.

RiskRealistic view
An order not arrivingHappens. Escrow and disputes cover most of it, not all, and not quickly.
Losing an accountUsually self inflicted through reuse or a skipped check. Largely preventable.
A parked balanceEntirely under your control and the most common avoidable loss.
The platform endingNobody can predict it. Every market that ended badly had a good stretch immediately before.
Linkage to youAlmost always created at the money boundary, not on the platform.
What the table saysThe pattern worth noticing: most of the risks above are yours to control, and the largest ones are decided before you ever open an address. That is good news, because the controllable part is the part that dominates outcomes.

The comparison nobody runs

Against doing nothing. Setup time, learning time, the spread, the waiting, the attention it takes to keep habits sharp, and the tail risk of a bad outcome, against whatever you were hoping to get. A lot of people do this arithmetic only after their first bad experience, and a fair number conclude they would not have started. That page is next.
