Welcome to Steemit, Valeriy!

I'm sorry to hear about Medium's blog policy and their shift towards censorship on crypto topics. I assure you, you will have no such problem here. The best part about the Blockchain is that once you post it, it's here for good, so censorship is nearly impossible.

I wish you great success. Don't worry if it takes a while to build up a following or see large earnings. "Slow and steady" wins here: post regularly about interesting stuff, and take the time to comment on other Steemit users' posts. Trust me, it's all worth the wait. :)
