Does that mean that I would have to buy specific hardware to mine Ethereum?

Yes, the best hardware depends on the type of PoW.

<p>I have been researching bitcoin mining and one thing has stumped me. Why is it that you can you mine so much more of other cryptocurrencies with a lower hash rate? I've looked on cryptocurrency calculators and it says that 1 TH/s for Ethereum makes a profit of about $2M per month, but only $53 per month with bitcoin. If your hardware is capable of producing a high hashrate, why not mine a smaller cryptocurrency and exchange it right away?</p>

Hash operations are not fungible.

Hardware that can produce 1 TH/s for Bitcoin's proof of work cannot do any hashes for Ethereum's proof of work.
