Hello dear @crypto.piotr

It has been quite a while since I've lost my interests with masternodes (it kind of happened once I discovered STEEM blockchain and I fully got engaged into becoming part of community).

I can understand you losing interest, as there hasn't been any sufficiently interesting advancement in the space since the introduction of Dash. Dash is solely leading the entire pack for now, with its engaging community, privacy and governence feature. In my opinion, it is the most functional DAO as of yet.

One thing that I always had trouble understanding is: should masternodes be considered securities? after all rewarding investors with dividents is security. To avoid being called security it would be better to burn tokens (the way binance does).

Interesting comment there. However, I have to disagree with your observation. Tagging a cryptocurrency as a security depends on how you describe a security. If you think a security is anything than pays dividend/interest for its holders, gives an ownership right and allows the holder to engage in the decision-making process, then surely it is a security. But if you say that a cryptocurrency that is decentralized, allows applications to be built on top of it, and has an engaging community that builds and upgrades it, then IMO that is not a security. It just depends on how one looks at it.

Also I came to realization, that most masternodes do not offer anything for their stake holders except of financial rewards.

That might not necessarily be true my friend. Other than financial incentives of the cryptocurrency, a masternode coin allows for applications to be built on top of it, allows one to engage in the decision-making process, gives a sense of belonging to the developers and community members and, has huge commercial and governmental implications. Masternodes are gravely underappreciated.

Thanks for the comment friend.
