I prefer the Target game, its slow but more sure. I loose on Crowd game.
CROWD requires more strategy, you should think between huge amount of shares for small number of inv (10-20), or small amount of shares and 100-1000 investments .
Of course, it it risky, because if new deposits are small amounts you can lose.
Also is important when you go in. When the value of total shares is low then is a good moment to deposit.
I would say that 101 HOURS and TARGET are more simple.
TIME and CROWD are better to build strategies.
