Surely a professional logo designer will know which loga is right for the brand that is needed, including in fashion, he will know how to conceptualize it properly and will not copy and paste.
A professional logo designer would charge more than:
The 1st prize is 50$ in BTC.
I know it is bad to count other people money, but in this scenario, for 50$ you get what you get for and should not expect design masterpieces.
I understand that the partial idea was to order exactly from cryptocurrency community and pay in crypto, but ideal variant would be to order logo design from a freelancer.
