Long story short, choose BTC if you want less risk and are happy with less profit. Choose DASH if you can accept higher risk for better profit.
I like dash as an altcoin very much, and I agree with you about the risk aspect of this choice. On the other hand, I think dash has a lot of upside potential right now and I don't believe its going to drop from around $70 any further. I certainly could be wrong about that, but dash is one of most popular altcoins with a strong community of supporters.
It has been almost a fantasy of mine for some time to be able to run a dash masternode, but there is no way I would spend over $70,000 to do it, even if I had that kind of money. Too bad the coin requirement is so high, but that's life. If I were Op I would go for the masternode option, even tho I like bitcoin more so than dash. Great way to earn passive income.
but that passive income isn't guaranteed right? After 1 year of earning if i buy back bitcoin again there is a possibility i get less bitcoin then i initially sold to buy 1000 DASH no? (bitcoin may rise to 4x next year and DASH may not)
