Speculative Investing
If you have some money that you can afford to lose, you can consider investing it in some speculative investments. These type of investments are high risk, hence the need to limit one's investment capital, to what you can afford to lose. Another characteristic is their popularity among investors, as in one would hear many people speculating about the investment. The aforementioned risk though may be worth it because this type of investments promises spectacular gains if one is lucky. Past examples are cryptocurrencies, IPOs of popular companies, and commodities. Bitcoin started selling at $1 in 2007 and now is trading around $80,000. Imagine if you managed to buy 1000 of these babies in 2007. You would be a multi-millionaire today!
