Have been there, still here, all hope to see $10 soon, but it can also go back down to $1's as well !
Fasten your seat belt for sure !
It's called a 'Stop Loss', put one in @ $3.40-$3.50 if nervous.
Yeah! Follow "stevem"'s suggestion. Then when you're sold out at $3.40 or $3.50......and GERN jumps to $4.40 or $4.50 (or $10), you can send "stevem" a Thank You note.
