When starting an investment we should evaluate the altcoin project very well. Investigate if it have use cases, what the community is like, the rewards system and what initiatives it is developing. Which altcoin project in your opinion do we have to get involved with to make a profit y why?
It does not seem as if you are interested in the long term health of the project and you are only interested in making money, in that case then almost any coin could serve the purpose, just a reminder, investing is risky by nature and when you add things like investing in the market not really knowing what you are doing and using leverage then the risks multiply themselves many times over.
You are a newbie so I would not recommend you to begin investing in altcoins right away, begin the way most people do with bitcoin and then if you still want to invest in altcoins then you can consider it.
