500k was not invested 43 weeks ago. Talk facts, don't stir shit.
LiteCoin if you failed big boy math class you shouldn't correct others.
Here I will "show my work" so you can follow along. Please take out a #2 pencil and a new sheet of paper.
Around the time of the closing Pirate indicates that there were ~500,000 BTC deposited.
Pirate interest obligation is 1% per day until repaid. That would be roughly 5,000 BTC per day on the 500,000 BTC deposited. At the time of my post it was roughly 6 days since the trust had been closed but funds not "yet" repaid.
500,000 * 1% * 6 days = 30,000 additional BTC owed. This evening it will be more like 35,000 BTC. If Pirate paid back a total of 35,000 BTC this week he would still owe 500,000. If he paid back 35,000 BTC every week until the end of time he would STILL owe 500,000 BTC. The only way he can pay down the debt it to repay faster than the rate interest is accruing. Given he has so far only paid back 100 BTC (or maybe up to 1,500 BTC unverified) the amount he owes has increased >30,000 since the trust was closed.
Another way to look at it is the amount Pirate owes increases by roughly $2,083 every hour, $34.67 every minute, $0.57 every second. Just in the time it took me to write this post Pirate's debt has increased by another $100 or so. Given your poor math skills by the time you actually understand this his debt will have increased by a couple hundred dollars more.
