I'm 44 and focused on retirement. Should BTC be an after thought?

I just started buying BTC in late November 2024. So, far I've put in about $3000. I'm currently in a position where I can invest $2,000 a month to whatever I want. My options are buy more BTC, pay off my house in 8 yeas instead of 26 years or apply it to traditional investments (S&P, IRA..etc).

I believe BTC will do great in the coming years, but as it gets more expensive, my $2K buy less and less. I don't know if I'll be able to own enough BTC by the time I ready to retire...I also wonder if bitcoin is a great retirement strategy?

If we pretend that the price of bitcoin goes up by $100,000 each year, I would have 1 coin by mid 2032.
