I want to hold steem coins, but I am not a fan of posting stuff. Can I still power up my steem coins and still earn profits as the coins go up in value without posting? Do I really need to post stuff to earn money even holding steem coins? Do I get more value to my coins every time I buy steem coins and power them up? I am just a bit confuse...please help clarifying my doubts I will appreciated very much since I already bought over 300 steem coins thanks to your posts.
