The OP talks about wanting to spend his BTC.
The responses are referencing getting rich quick and remembering the past dips rebounding.
Hilarity.
They don't care, just say the same all the time, to the moon blah blah.
English is not my main language, but was pretty easy to understand what OP was saying.
He wanted to buy something with BTC, in the process of getting bitcoins and doing the transaction the price changed.
