It is worth it if you are expert in trading, your 10k will be doubled or tripled depending on your tactics. Anyhow, you can just either invest in some potentially coins amd not with shitcoins. Or you can buy some eth and hodl it for a while for sure profits. 10k is just enough to start investing in cryptocurrency. Let us say the more you invest more, the more profits you will gain.
Yes indeed, you have some good points there, but we must also know that it is not only about gaining, If you can gain more profits, expect that you can also loss more. It is really like gambling with a thought of winning.
