OK, Thank you for your answer.
50'000 is a lot... could you consider then the possibility to offer a shared "like" masternode?
After DOB2.0 will launch we will have both DOBs 1.0 and 2.0
In DOB2.0 deposit named worth amount
In DOB2.0 not need send worth amount to DOB2.0 just need keep this coins on balance.
What you need to make DAC this is pay for registration DAC for 3 month
DOB2.0 is similar to masternode because need have worth amount on balance.
DOB2.0 is similar to staking because you will get accruals every day if you have registred DAC
DOB2.0 is similar to deposit because have fixed price for registation an expiration period.
