both classic and live on the same account?

yeah classic is going to go by your retail sub
and tokens can buy retail subs

ii do wonder if you will be able to buy and sell tokens in classic if so it might have a huge effect on the economy

They've already confirmed you won't be able to.

You will not be able to acquire tokens on classic with gold so you either need to keep farming BFA on your non-classic characters or keep buying non-classic tokens and applying them to your account to continue playing moving forward.

Although I honestly would not care too much if they did enable this since people still bought subs with wow gold it just was sketchier.

You cant buy or sell token on classic but you can buy retail gold here and buy token for wow classic game time .

Gold is a much bigger deal in classic than it is retail and it would honestly ruin the economy.

THe gold would still have to come from somewhere.
