Why would credit card users complain about that 180 days?
Their contract is immediate and goods are received.

Comparing to CC's doesn't work because someone takes the risk until the purchases clear. This is not the case with Bitcoin.

Are you saying bitcoin is ok, in comparison, if confirmation takes less than 180 days?

Confirmations take 10 minutes on average.

how can you say that look the present rate of bitcoin and then compare it with a month before. you will see that how fast the bitcoin is.

This doesn't make sense.

Further discussion on this will lead to the blocksize debate...

A block size limit increase could possibly ease the problem temporarily, but that is it.
