'$' denotes a variable name in the bash shell. If you provide the bare hash string without escaping it, bash thinks '$ethereum' is the name of a variable, whose value is null.
The '$' character absolutely must be present in the hash string; removing it will not work. You need to tell bash that the hash string is a literal value and not to expand what appear to be variables. You can accomplish this by enclosing the hash string in single quotes.
You can also simply place the hash string in a plain text file. But again, you must not alter the hash string, the '$' symbols must be intact.
