Bitcoin and houses, who is fooling whom

Several old comrades said to the post-80s and post-90s earnestly:

"Don't play with those virtual things like blockchain and Bitcoin.

In life, you should do something practical.

For example, work hard, and then buy a house and marry a wife in Beijing!"

A post-90s replied:

"You old comrades, you only know how to fool us.

Over the years, you have worked tirelessly to turn reinforced concrete with a cost of several thousand yuan into a house of 100,000 yuan per square meter;

If we don't find another way out and sell you a bunch of numbers and letters for 100,000 yuan a string,

how can I afford your house! How can I live up to this era!"
