i have one question....!!!!!!!!!! is this challenge true....?
i mean,  is it serous..?
i just smell like scammers here..?
because ...why no body till now cracked #64..although it is 16 digits length.
i will make more clear :
challenges 61,62,63 and 64 are same length = 16 digits.
how they cracked 61+62+63 and no one can crack 64 since july 2019...(last time they cracked #63)..?
