First of all, I don't know you personally very well, but I know a bit about your investment style because I often see you in the domain appraisal area.
Most of the time, you focus on .COMs, but in today's market investment environment, good .COMs are hard to register directly. You either get them through auction platforms or wait a relatively long time to sell them, unless there’s a hot trending domain.
There are many investment opportunities in the domain industry, and you could try changing your investment mindset or styles.
"Try multiple portfolio investments," such as new TLDs, ccTLDs, and the recent popular ones like .SI, etc. At your age, Im supposed that you should have some savings, and your focus should be on domain quality. You can register some premium domains appropriately (keep investment risk within 500%,which means domain registrations and renewal costs stay under $500).
Premium domains are often filtered by registries, so their quality is relatively more reliable.
In the past, my premium domains had renewal fees gradually drop from $1,000 to $500 per year, and of course, the quality gradually improved. If you have enough funds and have screened potential customers, you can also participate in premium domains even priced at $1,000 or higher. This is a good thing, but always keep an eye on market trends and maintain a reasonable flow of liquid funds.
Hope this helps you.
