I was looking at the logs for large bets and one guy is hammering 4 btc on his bets each time and winning. I would guess most of these operations dont throw that kind of payout and not require a few weeks to recover from overall business, that is why they need the backers
when an investment is good and it is returning good profit for you, there is absolutely no reason in the whole world other than needing the money for pulling your money out of that investment. so if it is good then keep it there until you get your initial amount out from profits and then you can put your mind at ease and enjoy the additional money you earn.
Well I said that with my cryptsy royalty shares, I did get back my money. I do wish I had withdrawn a little more over time as well, it was only a small holding so fees made it awkward. No big deal I guess, I was even to slightly ahead with btc rising. That was with speculative gains, investment wise we know cryptsy failed to do its job right and there is a risk with centralised holdings always to remember
