High risk/high return short term ideas for the clueless?

[ReasonsToBeCheerfull]

I know almost next to nothing about investments. A base level knowledge.

If you had £1000 that you were willing to risk losing completely but wanted to try to get as close to 100% return on it within a year, what would you do with it?

Open to all ideas including splitting it into parts and and doing different stuff.

I know I'd have to be looking at something with high volatility but have no idea about where or how to start looking or whether I should be trying to put it into a single share or a fund or what?

Go back in time 15 years and buy bitcoin, I often kick myself for not doing so.

Anyone with £1000 back then would have a couple of £million.
Seriously, maybe Space exploration related stocks or AI start ups?
You have to be ready to lose the lot.
Motley Fool website may have pointers.

I would personally buy £1k worth of Vodafone shares. Undervalued in my opinion.

Sadly it's easy to pick winners with the benefit of hindsight but there's a lot of investor interest in artificial intelligence. NVIDIA (high end chip maker) is up by more than 200% since the start of the year.

I produce a most bought and sold stocks in the U.K. each month for work and on the buy list most months is Tesla, Lloyds and the large cap U.K. blue chips.

But it's uncertain times for investing with inflation and interest rates so markets may well fall. You could buy a leveraged ETF based on one share - e.g, 2 x NVIDIA long or short. However they're not for the faint hearted. Commodity prices are also volatile so you can make big profits (or losses).

I now realise I've just repeated my earlier post, apologies. I guess I'm being vaguely consistent at least.l.l
