You can try. But when you release code under the GPL, you set the market
value of its functionality at zero (since an informed consumer will not
pay for it if it is available for free).

This means that it is unwise for another developer to pay to license your
code, because he is paying money for something whose market value is
zero. Likewise, a user who buys an enhanced version of your product
(if you publish one) will only pay for the value of the incremental
enhancements you have made.

If you publish your source under a license such as the BSD license,
they are not "taking" it. You have already freely given it, which is
a good thing.

What's more, if that person makes money from a derived work, his profit
(if any; most software companies don't ever make money) will likewise 
stem only from HIS improvements -- because the base functionality is 
already available for free.
