Yes and No. It all depends on if you win. Boxing and polypore are the more popular methods now. Sure it can be "good money" however it can also get you cleaned in minutes, especially polypore. I prefer boxing because it takes longer and gives both sides a chance of a comeback.
are there abilities in duel arena when staking? or are abilities disabled ?
They're is an option before the stake to disable abilities for both parties, however it is recommend to stake in EOC mode as you don't hit as high.
Correct, was tired when I wrote this.You mean legacy because you hit higher with legacy.
