Hello @david.jelista. You have some cool photos that you have shared but be careful not to post too frequently with little to no content within you posts. This practice could seem as spam and very low effort. I would also suggest making an introduction post for your blog so people can know more about you.
To help support your success and to help you from making any mistakes here on the platform... i wanted to share two posts i made to help newer users do well here on Hive.
Please check those out when you get some time and make sure NOT to do the things in there it warns against doing. I think this will increase your chances of support moving forward and accelerate your growth as well!
Yes, you need more Hive Power (or staked Hive) to have more resource credits to be able to post comments or posts on your blog. I would suggest reading those two posts I linked for you and then checking out the comment sections to see the questions and answers.
There is a lot to learn here but once you figure it out it's all much more fun. It's better to get a feel for how things work and connect with people than to just post and post. If I were you I would read those two posts and then work up an introduction post that will be more than just an updated bio.
I have a feeling that you are going to do very well here once you get your feet underneath you with a firm foundation! Greetings from a Texan in Sweden!
