Cronos is dual listed in the US and Canada, so unless you are in Canada, I'd personally look more at the US listed CRON, as it's got much greater volume than the Canadian listing version of the stock and is already close to the 2x volume requirement from just yesterdays trade, so can be fairly confident that it will reach the requirement.

Another reason for me, for dual listed shares, to go for the US ones, is that it would cost me more to buy and sell Canadian stocks.  This might vary from broker to broker, I'm not sure.
