        gas_coin: 1,
        gas_price: 1
      )

Sell coin transaction

Transaction for selling one coin (owned by sender) in favour of another coin in a system.

coin_to_sell - Symbol of a coin to give. value_to_sell - Amount of CoinToSell to give. coin_to_buy - Symbol of a coin to get. minimum_value_to_buy - Minimum value of coins to get.

Example
Minter::SellCoinTx.new(
