THE current bid of .09 and .17 on the ask for Bison creates a good opportunity for your TFSA,. IF you sell 1,000 shares at .09 and take this low price then swap something out of your TFSA for your Bison shares, eg. 1,000 shares of SGR at $ 3.13 will allow you to swap 35,000 of Bison shares into your TFSA. I guess if Bison trades at .50 cents then you will have $ 17,500 or if SGR was to trade at $ 17.50 then you would have the same. I see Bison reaching .50 cents before SGR reaches $ 17.50...just food for thought. Long On The Greens Traps7
