Welcome to Steemit @melek. I've written only few things from all that I've observed here. But I can tell you this the people who whine and abuse will lose their time, money, energy and their peace of mind on Steemit. There will be absolutely no place for such people here in the time to come.
Stick around and enjoy this place. Learn what works and contribute in the best way you can. Eventually your work will be noticed and you will shine! If you have any doubts feel free to ask here or on Steem.Chat. Cheers!
