Which crytids are most likely to exist? loch ness monster, mothman, bigfoot, chukapra ,mokle_mbeme or other?

I would think the chupacabra most likely to exist. On the Spanish channel they once had a news story about it. I mean, legit. They were at a farm and a lot of the animals were dead, and they showed the marks where the blood appeared to have been drained, or sucked out, whatever. All the other monsters only have grainy pictures, and never appear to have done anything but mind their own business. Wouldn't they have come across people more often, and have left evidence (i don't think unclear photos count) of themselves one way or another?
