I try to get bitcoin address by hand.

I set the private key like
 0x89888888888888888888888888888888889888888888888888888888888888888889888888888 8888888888888888888888

And I get the
1NLqpZnW746xjdAgnrTb56V4uZJiV4jjrU

but AFAIK, the privatekey should be between
1 ~ 0xFFFF FFFF FFFF FFFF FFFF FFFF FFFF FFFE BAAE DCE6 AF48 A03B BFD2 5E8C D036 4141

Why I can still get the address and if I send bitcoin to this address  1NLqpZnW746xjdAgnrTb56V4uZJiV4jjrU

What will happen?
Will I not able to sign the trans?

THanks a lot.

Do you think it's safe to use a  private key hash from 12-characters
