## calculating-equivalent-interest-rate.txt
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)

In cryptoland, cypherpunks get clever
Belief in freedom switches off never

So long as nodes are run, bitcoin stays untorn
Six an hour, new blocks are born

To honest miners, new coins are bestow
Going above 21 million is a no

                censorship on r/btc
              
          
    r/btc markets itself as a "censorship-free" sub. In reality it attempts to silence the voices of people it disagrees with.
A few screenshot examples of censorship

"Exploit code for the recent BTU attack - apparently this was posted to /r/btc, and of course, got censored. :)"
