Typical seasons set by the school year include summer, fall, winter, spring, but you can hire for longer time periods. When you post your internship on internships.com, specify the start date of the internship (you can choose a date and make it flexible or not). In your internship description specify the dates or length of the internship if you need something outside the typical seasons.
Our conclusion, NiceHash is really a good alternative to multipools and cloud mining service providers or mining rig leases and if used right it can give you some nice profit, regardless if you buy hashrate or sell your hashrate.
NiceHash is more then mining rig rental service. You can not rent individual rigs, but you can rent hashing power which is similar to renting multiple rigs with various speeds. Renting rigs is clumsy and exposed to various issues during rental (mining rig goes offline, can not achieve advertised speed, etc.).
