I bought 30.000 ADA, I trust this project.
Looking for I nice return in a few weeks/months 
Few weeks/months? More like years.. This project is a long term investment and as long as you HODL it for at least 2020 (when contract ends if I'm not mistaken), you should be good. I don't see this coin as a quick cash in/out investment.
I'm definitely HODL'ing it longer than a few weeks/months lol

I may not also considering these as short term investment, cause looking at its market and daily movement it seems to be slow but growing actually. I know ADA's capability and it really trusted that's why it is not left from the competition. Cardano seems to be good also, and yet still for long term investment same thing may happen for ADA.
If you're a short term holder better not buy ada because you'll just regretting it because you'll just see it falling now so if you're planning to buy just hold it long term like forget it for years that you buy ada.
I believe in its roadmap so I better stick to it. It will be a long way to go for all of us tho.
