21 (21) price, where to buy & arbitrage

21 1 exchanges

21 (21) trades on 1 exchange that Finder tracks live, across 1 spot markets. 21 arbitrage means buying 21 where it is priced lower and selling where it is higher, capturing the gap before it closes. The deepest liquidity is on Weex ($252 of $252 total 24h volume). Finder compares every 21 quote in real time to surface the best cross-exchange arbitrage spread, with live deposit and withdrawal status on each rail. Closed transfer rails are flagged before you act, so a wide spread on a stuck route is never shown as live.
