Ok. I spoke with @lothendriel an idea like that. I explain because, remember, I hate english and my idea can be different.
You have three assets (ACMT, DMT and ABC). You suppose 100 ACMT, 100 DMT and 100 ABC.
My idea, you sell an asset fund (I don't know if the name is "certificate of deposit"). Asset fund offers:
If you sell asset fund at 0.1 BTC, you return 0.11 BTC after, for example, 10 weeks. That means, you must give 0.011 BTC by week. The asset fund finish after 10 weeks.
Of course, the numbers are:
Dividens of (100 ACMT + 100 DMT + 100 ABC) x 10 weeks must be greater than 0.11 x number of "asset fund" coins.
I am agree with you in "arbitrage" and I believe, better "people transfer assets to you".
Advantages: You have 0.1 the first week per coin and you can reinvest. The 0.11 btc are the dividends of ACMT, DMT and ABC.
This is @dazme idea?.
