There's a large and ever growing list of coins with masternodes with prices for every pocket. Range from tens of dollars to hundreds of thousands.

Check out this site (there plenty more than in this list) here for a good idea of what's out there to start with.

Like with anything, there are winners and duds in the list. If you picked up a Dash masternode back in 2016, you'd be buying a lambo and then some more now.

Good luck, if you are looking to get in.
