Yes, most of the articles that I've read that's the minimum requirement. But if you are one of those who bought it somewhere around $20-$80 that's a fair price. Still, that's ethereum and the current price makes it quite expensive.
It's a better and cheaper coin I'd guess to have it on stake. Dash requires you around $72k to earn passively through its masternode.
Oh yeah, I almost forgot about DASH...
I guess the most sensible solution to those who can't afford 32 ETH like me could simply opt for an interest account. Won't reach 10% per annum but still better than nothing.
