I know diddly squat about investing. A couple years ago I invested 8k into a stock that plummeted and the 8k ended up being worth 1.5k. Since then, I’ve been very weary about investing again. But I have about 30k just idly sitting in a HISA and feel like that money could be put to good use to grow. I just don’t know how. Low risk and long term investment(s) preferably. Any advice will be appreciated!
