Although this is an old topic when 1 btc was precisely $27k but now 1 btc is x3 which is $81k maybe plan may have changed by now if many people where to explain what to do with $81k. For me I will not use all, I will leave set aside $21k into a non custodial wallet as a form of lump sum, split the remaining $60k in to three equal parts of $20k each, keep $20k as discretion and invest $40k into different business, watching it to grow while I use the $20k discretion to invest on regular DCA including buying dip while waiting for the business to start yeilding profit.

The type of business that may likely yeild profit as I thought of is livestock farming/ production. Another one buying shears from company, rendering services like starting up a mini transport company. Buying equipment for rentals etc. there are many businesses to do.
