They have implemented some new features with hashlets and hashpoints, go check people to hashtalk.
One question: Do anyone know whats the difference between Hashlet Prime 40 USD and other hashlets ? do other hashlets also provide stable payout like 1MH Hashlet Prime?
The other hashlets only mine whatever pool they are named after. Currently the Zen Solo Hashlet mines the same pool as the Primes, so the payout would be the same. Only difference is any future upgrades/promos will only be on the Primes.
