At the moment there are no fees on Whirlwind, not even for on-chain withdraws. Unless you choose to donate voluntarily it's completely free to use and all fees are on us. We will update the FAQ in the second post with more information
I noticed there is no option on the website for setting a fee so I was wondering: if Whirlwind is paying the fee when users move their funds from their notes to their wallets, what type of fees is Whirlwind paying? Are they priority fees? Normal fees? Low fees? I am asking because, due to the network congestion, if low or normal fees are paid, transactions can be delayed for days.
The 1% monthly return is the minimum we guarantee for as long as the campaign will last, we adjust the distributed amount every day to reflect this considering the multi-sig balance changes [...]
In order to reward early depositors we were considering setting a 'floor' for the total rewards paid out at 0.5BTC a month, meaning that with the current balance a depositor would receive 4.5% monthly return. This figure would go down continuously until it comes back to the usual 1% when the balance hits 50BTC and will continue like that until our Anonymity Set goal is reached.
Here I am not sure I understood correctly... is the interest 1% or 4.5% and dropping to 1%? (By 1% I mean 1% per month, respectively 1/30% per day -- same for the 4.5%.)
Have you considered how long you will keep this campaign running if the deposits number simply does not grow up to 10.000? Will you wait for 1 year to reach this number? 2 years...? Will it continue endlessly if this number is not met?
