Day trading Alpha pack tokens built on an altcoin, Steem is risky business. I'm glad it worked out for you, you can also get lucky playing dice. The returns from mining these tokens will greatly diminish as more people are mining the tokens. The price of these tokens could also trend to zero so I don't think they can be compared to traditional investments at this time. In the future I would expect a significant risk premium attached to mining Leo although earning a return in a few days from it that is higher than being invested in traditional assets for years is nothing but luck. No one should expect that.
