Ziggy - sell half your holding once its doubled, then worry what to do with your "free" shares. Protect your capital.
These sub-pennies are notorious for taking $$$ from the uninitiated. The old-timers make money off the noobs.
I bought in too high (.0011) averaged down to .0004 when it could be bought at .0002 - sold half at .0008 and am just waiting for it to pop back up again.
Do not get greedy. A guaranteed double or triple beats the heck out of a possible 10 bagger that turns into a loss. Make a plan and stick to it.
