Buying 1 Bitcoin

Hi everyone. Currently sitting on USD 120k cash (thankfully I don’t need that money in the sense that my life won’t change if I lose it all).

I am thinking of buying 1 Bitcoin, but have no previous experience with Crypto.

I understand this is a bullish sub but would appreciate your insights on whether to invest that money in one bitcoin or not. Also, would like input on DCA (for instance 20k a month for 6 months) vs lump sum.

Thanks!
