Same concept, you buy property with a mortgage, value increases, re-mortgage to release equity to use to buy another property.

Repeat

Only difference, property typically doubles in value every 20 years, Bitcoin typically increases 20 fold every 4 years.

Current wealth of the planet $454T

If Bitcoin 20X’s twice more, then market cap of Bitcoin will equal total planet wealth.

Therefore $MSTR only has one full halving left till $BTC starts to flatten.
