| JoinMarket yield generators earn money on an unpredictable basis. It's worth calculating | |
| the equivalent interest rate as if joinmarket was a savings account. | |
| We can make a model of a bank account that takes deposits and withdrawals at any time and | |
| where the balance accumulates interest, then the parameters from a JoinMarket yield-generator | |
| wallet can be inputted to obtain the equivalent interest rate. | |
| We know that the present value of a bank account (P) grows to the future value (F) determined | |
| by the interest rate per unit time (r) and time (t) | |

JoinMarket has a tumbler application which aims to send bitcoins in a way that delinks the origin and destination.
I have some thoughts on how and why to improve the tumbler algorithm.
Feel free to bikeshed some of these parameters (averages, counts, etc), as my important points are about other stuff.
