Please , anybody clarify my doubts

why Eng to Bee?

if u sell Eng who will buy ?

Steemengine moving to Hiveeng then if anybody buy Eng what they do with it?

what happen if steemengine have to stay on both chains ,one for Eng for steem and new one Bee for hive ,because of the fees for tribes move on to hive and they dont want to pay for it or they stay where they are.

if steemengine migration for free on hive blockchain,why tribes have to buy bee ?

they have Eng then why hiveengine creating Bee ,tribes can use eng on hiveengine ?
