The dynamic interest is invented for bagholding (i.e) the more you hold, more the interest. So you will naturally be tempted to stake as much as coins as possible.
So when many coins are staked, the supply is lowered, that which increases the demand.
Lets consider you are holding 1 million pesa for staking and earning a interest of 200 pesa's a day.
Today 200 pesa's aren't worth a few dusts of btc.
May be once we have enigma, sms & smart contracts implemented and the value had gone for around 20k sats, you will be earning around .08 btc's per day.
When i had 1m in wallet, interest was 5-6.3%, I do not like that the percentage depends not only on me.
HBN have 100% POS and the demand is no crashing.
There's a twist. You need to hold your coins in your wallet for minimum 10 days to get 2% interest. Thats a difficult part in the crypto, where there are many deeming to become a overnight millionaire.
And when coming to HBN, it has a very active hero rated developer and the community is still on.
