It all depends on the coin you are looking at, which project do you want to stake or be apart of a master node?
I didnt know particular name of the coin but i had seen many masternode coins on this website
https://masternodes.online/.Can you suggest me better one becasue i m new in this field so i dont have much proper knowledge
i recommend you to not buy those 'Masternode' coin or project based on those exchange entirely.
if you are not sure about it yet,why rush it out ? you can keep it and do your own research,until you understand very well about it.also from my own experience,the majority who offered me those kind of 'Masternode' for only or below $1000 were scams.
they were looking very good when i saw it at the first time,but what happened with them after they reached the exchange ? the price slowly turned into dust in a single month.
and actual profit ? nobody knows about it,because everyday and everytime it will decreases.
it is all about weight and total masternodes that are online when you are staking or hosting masternode that time
