That's a huge target buddy! But in the basketball we say that the game is over only when the siren wails. That means you have plenty of time to reach you target!
Speculation and trading are also great chances to create a small compounding interest. I am doing an escalating path onto SLP and TRX tokens, accumulating more and more as the market goes up and down. My target is doing 1% on both positions I have, every day. It's not easy, I am not able in doing it every day, but since one month, I am more or less at 10% on both positions. Keeping some smiling grinding and some discipline, the results can be interesting.
