The idea that anyone could securely hold MPAs long term in their wallet and receive better 'interest' rates than that FIAT banks were offering was (and remains) a powerful message which had myself (and a lot of other users) sold on Bitshares.
During the migration from BTSX (BTS 0.9x) to BTS 2.0 we removed 'socialized yield' due to '[yield harvesting](https://bitshares.org/blog/2015/06/08/lessons-learned-from-bitshares-0.x/#socialized-yield-is-broken)'. I believe that its removal without an established replacement income stream for asset holders was a mistake (one that we can amend).
The last monthly gathered fee estimate was approximately 1 million BTS per month which is approximately $330,000 (not an insignificant sum), of which 80% was distributed to the referral system (20% goes to the reserve pool).
* The potential for profiting more by holding your assets on the BTS DEX than within a traditional FIAT bank (without taking on risk) could drive many new users to pick the BTS DEX over centralized banks for storing their savings in the future.
* An increased demand for MPA leads to an increased MPA supply and thus a reduction in the quantity of liquid BTS (since 200-300% BTS are locked up as collateral for each MPA token).
* An increase in MPA supply potentially encourages greater MPA liquidity on the BTS DEX.
* Other cryptocurrency platforms offer profit-sharing/dividends, such as [Peerplays](https://github.com/BunkerChainLabsInc/peerplays-profitshare)/NXT/CounterParty/DigixDAO/LBRY/Waves/Dash.
* By incentivizing Bitshares users to hold their BTS on the DEX instead of on centralized exchanges we minimize the risk of said centralized exchanges having a massive voting weight with which they could disrupt BTS operations by voting maliciously.
## Implementation of Peerplays profit sharing mechanism
The Peerplays developement team developed [profit-sharing code for the Graphene toolkit](https://github.com/BunkerChainLabsInc/peerplays-profitshare) approximately one year ago, they have repeatedley given permission for the BTS DEX to utilise their developed profit-sharing code ([case 1](https://bitsharestalk.org/index.php/topic,23981.75.html), [case 2](https://steemit.com/bitshares/@cm-steem/bsip-019-draft-introducing-profit-sharing-dividends-to-bitshares#@peerplays/re-cm-steem-bsip-019-draft-introducing-profit-sharing-dividends-to-bitshares-20170620t032010758z)). A large portion of the work required for this BSIP may already be complete.
## Fee redistribution variables
The fee redistribution values should be discussed thoroughly and either decided by the committee (smartcoins) or the MPA issuer (non-smartcoin assets such as Algorithm based Assets).
* MPA dividend prioritization : Equal split between all MPA (subsidizing less active MPA), or proportional to [trading volume|MPA supply].
## Basis for distribution within sharedrop timeframe
* Dividends is paid on a scheduled basis as opposed to on user demand
* Dividends are paid based on MPA asset holdings
* 'Coin-age' of asset holdings
* Split of network fees between MPA tokens, either on an equal split or proportional basis.
## Whitelist/Blacklist options
* Configured by the Committee or the MPA issuer.
* An optional whitelist could provide increased control over who is eligible to earn dividends on their MPA holdings.
* An optional blacklist could prevent exchanges/services from earning dividends/interest on MPA (incentivizing holding MPA on the BTS DEX over centralized exchanges).
A quote from the '[Socialized yield is broken](https://bitshares.org/blog/2015/06/08/lessons-learned-from-bitshares-0.x/#socialized-yield-is-broken)' blog post:
> "Under BitShares the BitAsset holders receive a yield simply by holding BitUSD. This yield was between 1% and 5% APR on average. Unfortunately, yield harvesting can happen at any time by someone shorting to themselves to gain a very low risk return and undermining goal of encouraging people to buy and hold BitUSD. The yield was funded from transaction fees and by interest paid by shorts."
* Rather than paying profit to shorters on demand, this BSIP proposes scheduled dividends against BitAsset (MPA) holders via the redistribution of network fees.
* If we simply took a snapshot of user asset holdings at the immediate time of dividend issuance then users could create the asset immediately prior to the scheduled dividend after which they could settle the token back to BTS. To prevent this behaviour, we need to take the age of asset holdings into account.
* Thus BSIP19 is not vulnerable to the 'yield-harvesting' issue that was prevalent within 'Socialized Yield'.
## Collateralized Bonds
The concept of "[Collateralized Bonds](https://bitshares.org/blog/2015/06/08/lessons-learned-from-bitshares-0.x/#socialized-yield-is-broken)" has yet to materialize within Bitshares 2.0, so in effect we cut asset holders out of fee redistribution (by removing 'socialized yield') without providing a replacement source of income for holding assets on the Bitshares DEX.
