$180 would assume Tezos surpasses Ethereum in every possible way. And then, on top of that, the market cap of all cryptos more than doubles. To be clear, I don't think that's outside the realm of possibility, but I'd love to see your thought process.
I truly believe we're still in the early stages of explosive growth in blockchain technology and value. Ethereum has a big lead right now. I'm hopeful Tezos can catch up, but they need to prove their concept first.
