Dash masternode cost you around 20k USD. Meanwhile, it can only give you 2100 yearly. Imo this is quite small.
It means it takes around 9,5 years to get ROI, but you can also sell your Dash used for masternode anytime.
Getting 5,7 usd daily seems worthy enough. However, it totally depending on the price of Dash.
9.5 years is a long time to get returns. I do know that it was profitable back in the day but right now, the barrier to entry is super high and returns are not even convincing one bit. It's also worthy to add that Dash doesn't have the same interest and attention it used to have and that is very reflective in the coin price as well. A very huge gamble imo and there's no telling where Dash price would be in the next couple of years.
The masternode era has already passed, and i guess the price will never go up. Things worsen with so many exchanges are also against the privacy coin.
