Selling my home and want advice on how to invest.

I am getting married and moving into my fiancés home. I will have about $200k and want to buy 3 BTC and HODL to my hardware wallet long term. Should I just buy all in one go or DCA? Seems we have bit a bottom but I really don’t want to trying to time the market.

I also want to buy an investment property to use as an Airbnb. Should I just put the money in BTC for 6-12 months until I’m ready to buy the home? The volatility of BTC in the short term worries me. Thoughts?

Oh and don’t bother inboxing me, I’ll ignore!
