I saw this long ago, this site is as usual mining site that consumes computer power. I'm asking about some real faucet mining

As we all know, mining means setting up a ring with a high-end ASIC miner, mining BTC, and ETH.
But is it possible to mine Goerli or Sepholi ETH? I learn this info from chatGPT.
I want to know that, if it is possible, then it will be great, therefore getting Goerli/Sepholi ETH is now very time-consuming.

I saw many small startups growing based on crypto themes. Several groups create crypto merchandise to sell on platforms like Instagram profiles and websites.
Some examples are
https://www.etsy.com/market/crypto_merchandise
https://cryptogoodies.shop/
https://cryptowardrobe.com/

Now I'm thinking that I'm gonna make these kinds of merchandise and sell these platforms. But don't know about the market potential. Is the people of crypto ecosystem are really interest to buy crypto merchandise stuff?

As we know, Yield farming is a great way to earn passive income on an invested crypto. In yield farming, we see that many stablecoin pair have much higher APY rates compared to the traditional rates.
Some examples are here from the defilama

My question is that if anyone takes a loan at around 10 - 12% interest rates and invest in stablecoin pair to earn a decent 16 - 18% APY interest on various platform. Now there is a margin of 4 - 5% to earn. Is it possible in reality? Because many factors are working here.

• First of all, there is always a risk of hacking the platform, seeking higher APY, many users invested in small pools, where there is a always risk.
  
• The rates fluctuate regularly (every 3/15 seconds).
• Have a change to rug pull.

Despite all factors, is it will be profitable to follow this way, 'take a loan from one place and invest in another for getting higher APY %
Although the APY % is very low, investing a large amount could bring a large APY.

Can any one earn like this? If yes, what things need to remind before investing?
