ok then, here is my question:
Where is the key? Is the key located at the 3 virtual coins or it can be found in your answers?
hope you can answer this
Well it definitely has something to do with the number 4 since he is saying ''4 the key'' and not ''for the key''
Binary-coded decimal, or BCD, is a binary encoded representation of integer values that uses a 4-bit nibble to encode decimal digits
Perhaps something to do with this?
