Hi
even if, or when you quit your "job"...
you still got to put in work managing your portfolio of domains.
so, you're just trading one line of work, for another.
best to keep your gig and do domaining at same time, if/when possible.
as seen with covid, you never know what can happen.
if your job was paying healthcare, dental, life, retirement plans, along with SS deposits,
then when you quit, now all that has to be covered by domains.
if you got a home, family, and expenses associated.... all that has to be covered by domains as well.
sure, it's possible to make more money, buying and selling domains, than a regular job.
but as your lifestyle changes accordingly, you might have to work harder just to sustain it.
imo....
