$1 Million with memecoins, now what?

I have been trading solana memecoins for quite some time now and with really fucking much luck and degenerate trading, I have managed to make a little over a million dollars. I know this might sound not realistic to those who are not familiar with the space, but it is truly the only space where I have seen kids like me make insane amounts of money in matter of hours.

Should I just throw the money into S&P 500 and compound that? Do I throw the lump sum in or DCA? Or should I look at any other investment opportunities?

I have also been thinking about buying my long time dream car which would set me back around $80k. Yearly maintenance should be about $2k. Would that expense be fine considering it is 8% of my net worth? I am aware that it is not a good choice financially speaking, but that damn car has been on my mind for years. Would be great to have some outside opinions on this matter.

I am still attending university for 2 more years and my monthly expenses are usually under $1k.
