Well if you have 100 bitcoins in your wallet and then you can wait for price hikes in order to be rich but those getting bitcoins from micro sources in bits are just not being realistic with themselves. So go ahead you can dream but be realistic.
Even if we earn a small amount of bitcoins but it is not a reason why we should not aim for more, in fact we can use that amount to invest or trade and grow it. This is not a possible dream as we have seen there are people who made it possible, we should be inspired and take a bigger risk now, it's not too late for us as long as we have that perseverance and use our passion to make money.
