The best motivation we can get is the opportunity to earn. There is no better motivation than that. If you notice, the market keeps on dropping and there will be a time that the only way for it to go is up. That is why we can take advantage of the cheap price and buy as many coins as we can. We might not get this kind of price again. Think of it as a discount that will only last for a short period of time. You can sell later when the value appreciates or if you are happy with the price.
