Buying put options of a NASDAQ stock as an EU citizen?

I think the world has gone mad and a certain currently hyped stock will collapse. Like, it will lose third to half of its current market cap in, at most, two years. I would like to put a little of money where my mouth is and based on my understanding, short selling is dangerous in case I am wrong but losses on put options are limited by the price of the option itself.

So how do I do this?

I am not experienced, I keep my retirement savings in an S&P 500 tied unmanaged index fund.
