Hi, I have a high risk profile.   I think I can invest 100,000 US dollars over the next month. This is 75% of my savings, from my entire life.  It's a one-shot deal.   I accept that I could lose all my money and have no savings.  I am early middle-age.

I'd like a 10x return at least.   I do not believe I am an idiot, nor do I believe anyone can always pick winners.
20x would be even more awesome.
I am interested in about a year time horizon starting the clock from April 10,  2021.  

1. How would you invest my 100,000 and over what time horizon?  I'm thinking for alt-coins you have to get in near the ICO or within the first month to realize a 10x.  
2. How many alt-coins would you suggest I focus on?  For example, 10,000 each on 10 alt-coins?  or 5000 each on 20 alt-coins?  Or 1000 each on 100 alt-coins?  
3. Names of specific alt-coins where it's not too late to realize 10x gains if you are new to the market in April 2021?  I see some YouTube videos and charts, and it seems I am 3-4 months late to the game.  Had I just invested in January 2021 in those projects that I like, I would easily have had a 3-5x already.
4. Stepping back, am I too late already to the alt-coin market?  Should I just do  bitcoin which I view as low-risk?

thank you!
