question How to find best domain and sale it wisely.

HI
your question has too many variables, to give simple answers

however, it starts with your budget. as in, how much you can afford to spend for a domain.
next, is picking domains that sell themselves.

the more money you have, along with knowledge of what a quality domain is....
can put you in position, to hopefully, acquire a domain that will yield a nice roi. (return on investment)

patience, is last, because it may some time before the right buyer comes along.

i suggest you keep reading and learn more about what goes on in between the lines, than what's written in them.

imo...

thanks for the golden lines .

--as being new bie budget will be not much first priority is hand reg next is accruing below 50$/100$.

$50 or $100 is not enough my friend. You need at least a few thousand US Dollars to earn regular income. Don't read too much YouTube stories. Read here practical stories in Namepros.com, that will help you a lot.

The best domain will cost you a fortune, if not a leg and an arm. Are you ready?
