I just wanna learn from the opinion of other persons here, what do you usually look out for in any project before deciding to invest in it, maybe mid or long term investment?
There are the chances for you to get misguided if you still look for altcoins to invest. It would be better if you choose only bitcoin for your investments because it has a lot of possibilities to get you big returns compared to any altcoins. With respect to your experience on this forum, I am suggesting you to go for only bitcoin and if you too much concern about altcoin investments, then you can invest with ethereum as well.
another thing is the project itself what it can contribute to the industry, the roadmap is very important, all good projects are long term investment, a good project is always a long term investment.
All good projects are good for long term investments but the catch is how to identify them. This is the reason, new people should simply stick within highly known coins like bitcoins and etehreum. Moreover, investments with bitcoin definitely can get them up to 10x returns once in 4 yours with comparatively less risk than investments with altcoins.
