Anyways, before this goes off topic, I'll explain my reasoning above and contribute more to the thread. (cause business):
Investing in small companies has a greater return, especially if they become successful, but it has a greater risk. (losing the 1k) Since I just had 1k, I'm guessing that I would be able to throw that amount wherever I want. In my opinion, daytrading and stocks is too much of a headache, and I already invest an amount of my salary into long term stock options.
They are a good and "safer" option though, as opposed to investing in a small business. Also, your money isn't sitting idly and will have a higher yield with a low risk, which makes it better than saving it. Therefore, you're technically not saving money but spending money on assets that may increase in value, which is usually the case if people are patient. However, safer options don't have a great return, and are not as fun.
So, I'd rather play around with the amount and invest in something I love and believe in, if I were forced to put it into something. (This means zero risk to me
so might as well have fun)
