I agree with you.  Hourly paying pools should add a possibility for users to choose minimal withdrawal threshold.  it's not convenient for CryptoHub to overload the platform adding tons of deposits of ridiculous amounts, that sometimes can be lower than 1 sat in equivalent.  
Even on mining into local wallet such tiny amounts will cause problem: you will pay high tx fee when you will send that coins and even you can get error "Transaction too large" and you will need to perform dust cleaning. if coin is PoS a lot of small inputs will cause high CPU consume. So consider the consequences when using that hourly paying pools
