I'm not sure the usage of Metatoken? is it used just for transaction to reduce/no transaction fee? for example to transfer bitcoin into another MHC wallet, convert it to metatoken first, send it, and convert it back to bitcoin?
Fast speed + metahash coins are needed for forging to have a node
Additional information you can find in the yellow paper
Why do we do to the account after purchase? To those who cant download metagte wallet?
