I rarely make a website based on fads or something the government could regulate tomorrow and make your site worthless overnight.
I try to stick to products and things that people need and use every day. When you chase after a niche you are usually too late already and have to play catch up.
I have sites on coffee, cars, books, health, checks, NASCAR.
Whenever I chased a fad it failed and I lost interest quickly because it wasn’t something that interest me and I was trying to chase money. Before I choose to make a website in something that is hot and trending I ask myself would Warren Buffet do this.
The latest example I can think of is spinners. They came and went so fast the $1 stores don’t even push them. My friend Jim who does farmers markets told me he was gonna go out and buy 10,000 of them because that all he saw at all the booths at the Farmers markets.
I asked him if he saw anyone buying them. He didn’t know. He saw people picking them up but they weren’t buying the way he thought they were.
I was in Circle k earlier that morning and saw the spinners on the checkout counter for 25 cents. I said to myself the fad is over. I quickly told him that he shouldn’t buy any and that was the best advice ever.
It is ok to chase a fad if it is absolutely something you are interested in and you understand it as that. You should have your website base made and making money beforehand though.
