Quote from Crucis:
Even with the wide b/a, you can still make money.
That's absurd.
You might as well say - if you buy before it goes up and/or sell before it goes down you can make money.
You can make money with any trade any any price - but only if the item you trade makes a favorable move.
Bottom line, unless the margin factor is critical, it's silly to trade an underlying with with wide b/a spreads when there is a liquid alternative.
