JUST WENT THOUGH IT, IT WAS NICE TO READ AND VERY INFORMATIVE
Thank you, that tutorial was done by a person who created a masternode with the FLITS app, it shows how easy it is to create it with a simple app
But there are more options, like using a masternode hosting services or for advance users if they want they can use their own VPS
but, at the end by having a masternode your participating in the the blockchain
I learnt a lot from it, I will try it out later in future and give my review on the app, it really looks simple and fast at a glance.
