It all depend on the Company.
R/S could be 10:1,100:1, 50:1, 2:1.. etc
Most penny stock tend to do big R/S like 100:1, then your 100K will become 1K.
No R/S for this stock until much higher up, I think.(10cent level??) Many subpenny had reach pennyland with similar share structure as MMTE before. I was lucky to be in 4 of them. LD*R - $0.01, H*NT - $0.0186 and going, HTD* - $0.024, A*FX - $0.09
There are plenty but those are the one I invested and have O/S around or higher 2Billion
Just make sure you get your original and some profit on the uptick to play it safe. GLTA
