What is the best coin to invest now? No shilling.

This is not a new question to this community or even anywhere else, so pardon me for that. But with almost all coins down by more 50% from ATH, I believe this is a good time to invest even as a short-term strategy to get some cool ROI by end of this year.

Here are some considerations:

No ICOs, though that means no lambos or to the moon. I am absolutely fine with it.
Would prefer to diversify the portfolio to at least 4 coins - 40%, 25%, 20%, 15%.
Please avoid shills.

Hope to get some sound investment advice from this vibrant community, it will be useful not just for me but for others as well.
