When ACTUALLY using bitcoin to buy and sell goods, is there a way to take its current price ($22,xxx) and find an actual value to it?

When ACTUALLY using bitcoin to buy and sell goods, is there a way to take its current price ($22,xxx) and find an actual value to it?

Because if i sell my valued item at say, 22,000 worth of bitcoin. Tomorrow, there could be a crash which brings it down to $1000 or less and i've essentially traded my $22,000 item for worthless bubble money.

Is there any term to search or people to talk to who understand bitcoins true value?
