Short answers — each links to the relevant chapter of the Wasabi documentation for depth.
No. Your keys never leave your wallet — the coordinator only collects signed inputs and outputs into one transaction. Wasabi refuses to sign unless your exact coins come back to addresses you control, so the worst a malicious coordinator can do is fail the round. More: FAQ — Use Wasabi
coinjoin.nl charges a 0% coordinator fee. You pay only the bitcoin mining fee for your share of the transaction — and because a coinjoin batches many payments into one transaction, that share is often lower than a solo transaction.
As little as the WabiSabi protocol allows: registrations arrive separately over Tor and are blinded with cryptographic credentials, so the coordinator cannot link your inputs to your outputs — that unlinkability is the whole design. More: FAQ — Bitcoin privacy
Wasabi skips coins that are too small to be economical to coinjoin (dust), and our weekly round starts once enough inputs register — 26+ for the Sunday round. Practically: anything above dust size can join. More: CoinJoin in depth
Yes — your wallet must be online during the round to register, sign, and confirm. If you disconnect, the round simply continues without you; your coins never move without your wallet's signature. More: CoinJoin in depth
Nothing is at risk: a failed round produces no transaction at all, and Wasabi automatically joins the next one. Rounds fail when participants drop out — it costs you nothing but time.
A coinjoin is an ordinary bitcoin transaction that several people sign together — batching payments for lower fees is its own justification, and privacy can be a side-effect. Rules differ per jurisdiction and exchange; this is not legal advice. More: FAQ — Introduction

The most recent successful coinjoin, straight from the coordinator.
Bonus: coinjoin with the keys on a hardware wallet — built for larger-value coins. Your keys never touch the computer: even a compromised PC can't steal them, and the device itself enforces the coinjoin policy (your coins can only go back to your own wallet, within a capped fee). Unlock, approve once on the device, and rounds sign unattended. Under development.
