If your "roi" is only in the coins created then yes wonderfull roi but if u cant exchange those coins for BTC or USD they really are worth nothing anyone can create a masternode coin or have one made for them for less then 1k usd (way less) its up to DEVS to add value to the coin/chain by having innovative projects attached/associated with/ to it.
This coin does not talk at all about how this value will be created and thats why at this point this coin has 0 value could it become more valuable in the future maybe but since there is no information about dev team / whitepaper or anything that actually matters on the roadmap so there is no way to judge if there will be value added in the future.

Most of the these "Masternode" coins are just blatant money grabs with 0 development beeing done devs talk about the future but never deliver and as soon as no one if buying their masternodes anymore .. @ 0.7 they will stop responding because they are busy with their other clones that fools are still buying.
