Max,
U can buy bltra just like any other share.
Will give you the right to buy blt for 2c plus a free 4c exercise price option for every 4 held.
Last traded price for bltra was .003 so if you bought the last price you would need to cough up .02 + .003 =
.023 per blt plus u get the free 4c option.
I sold my bltra's for 1.1c (thank u to the sucker who bought them at a fat premium)
