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.
Ethash is the proof-of-work function in Ethereum-based blockchain currencies. It uses Keccak, a hash function eventually standardized to SHA-3. These two are different, and should not be confused. From version 1.0 Ethash has been designed to be ASIC-resistant via memory-hardness (harder to implement in special ASIC chips) and easily verifiable. It also uses a slightly modified version of earlier Dagger and Hashimoto hashes to remove computational overhead.
