A simple question, If i buy 1000 DASH with Bitcoin and and run a masternode, i will generate passive income. My question is will the end result after 1 year (initial deposit + income) will be greater than if i decide to HODL bitcoin and don't run a masternode ?
Ideally and if all things being equal, running a masternode with DASH would have been better but you can't guarantee this absolutely as bitcoin still dominates the crypto market. The crash of bitcoin will still affect your ROI on running DASH masternodes. In the long run i would definitely encourage you to run a DASH masternode other than just holding BTC.
I want to earn passive income but it has a risk right? What if DASH price falls after one year and bitcoin price keeps increasing,that can happen? or Bitcoin and DASH price directly proportional in long term?
That is not a problem as you would always have some DASH coins to sell so far as you are running a masternode. It's always better to go for a constant passive income.
