First of all take that amount seriously!
6$ is good, small and if you want a project then it's gambling. With gambling you can get 1$ daily with low risk.
Until they go to 25$ then start trading or investing in HYIP. Just know that your goal is 100$ then start trading.
I guess that you as a normal person who can type a complete sentence. You can gather more 4$ or more 20$ and go to Gamble.
6$ by gambling to 25$
25$ By HYIP to 100$
100$ start trading in alt coins
Anything that you mention is considered as highly risky, you can better send it or donate to someone who you do not know, than investing in HYIP or gamble them.
HYIPs are made to make some cash for the owner while the investors are the victims. For a casino, is the lucky always the bank (investors, owners) in the long-run.
I would store that amount and forget it for years, alternatively, I would invest them in crypto-assets (tokens) and do the same way.
