I only bought my first domain sometime in 2017. It was d4rkstar00.info and it was ugly. I ended up scrapping that domain out.
I didn't buy another one until later that year in August. I bought hyperdefined.space, and it was the best idea ever. I have loved that domain ever since.
However, I never knew now many TLDs there actually were at the time. Fast forward to now, I have a better knowledge on what there is.
I ended up buying hyperdefined.wtf and hyper.rip just for the fun of it. Turns out, I actually really like hyper.rip and now use it as my main domain.
The other two domains just point to my site. However, they don't have the subdomains setup because it's really annoying to.
