Which in other words means it is all a game of nerves. Even in the traditional business, initially the marginal profit is not so high as compared to the invested money and the expectation but as the trend spreads overtime, the brand is something that also attracts costumers then.

Same is the case here; you invest and do not expect quick money which will help to coupe the market uncertainties. After sometime, you start noting the growth in the value of your portfolio and in the third phase, when the value of your portfolio exceeds beyond the point you had set to earn, cash out. So do not sell yet for you still have to enter your third phase.
