If you exchange $6800 for 0.1 Bitcoin today, you have the same amount of money for which 18 years later millions of people all over the world will spend their resources, time and labor for ~10 minutes to produce 0.1 units of a money, whose total amount will be exhausted by 97.66% til then.
These $6800 will be 0.000...1% of the US dollar money supply in 2044, when ~0.1 Bitcoin will make up the block subsidy of a Bitcoin block reward. By then that $6800 possibly won't even get you a month’s groceries.
