3K WAVES is around $6300 at the current price, so not that much comparing with some other big crypto masternodes. Also it is more of an investment, if you belive in the project and that price will go up, your node could be worth few times more than now.

Do you know how much coins you can earn running full node, or maybe have any link to such info?
Oh sure. You can see the profitability here:
http://dev.pywaves.org/generators/In the column "Average Gen. Balance" shows the amount on the balance of the Full node, and in the column "Waves fees" - the approximate number of Waves, which this Full node receives for the mining per day. To run the mining now the minimum necessary balance of 1000 Waves.
Interesting information. Looks like running a waves validator with minimum balance of 1000 waves (over $2k) currently would only make ~$10/year.
