Nonsense. It is lower in value when measured against anything. You are not deep
Probably OP means that bicoin is the measure of price, so price of bitcoin cannot change by definition: one bitcoin always worth one bitcoin.
I think OP means that if you use BTC for its intended purpose, to buy goods and services from the merchants that have adopted bitcoin, you will get approximately two thirds less than you would have when BTC's price was $1,200.
