Delage ada or create own staking?


anybody can give me the answer: what is better (mean return in %) create own pool or delegate ada in other pools? I am working as programmer, so I am sitting almost entire day near pc


Pool owners need to make a large commitment themselves. If you have a lot of ADA, as well as all of the other requirements, then it could be worth doing.

Where I can find these requirements?

The main source of information on staking is here.

Anyone seriously interested in running a pool should join the Telegram group @CardanoStakePoolWorkgroup.

This is not really my area, others might know better sources on your specific questions.
