At first one can think as Satan Lucy did, there's logic to it of course.
We lack a lot of data on others, as well as of the trustworthiness of the one offering us (for all we know it's a scam big time).
So, based on current economics and the realistic outlook of how likely it is to disappear, we must aim for exactly day 6.
On day 6, you will have amassed 1 x 2^(6-1) which is 32,000 I am presuming USD.
Now, if being extremely conservative, you'd want to wait to only Day 4 and take 8,000 but I will trust in God, if he doesn't want me meddling with those promisers of money and that money, I'll accept it.
An amount of 16,000 is okay that can be the start of something huge but takes more years to snowball into what 32,000 instantly can get rolling.
with exactly 32k rather than 16k you can begin paying off old loans, buying things, whatever on the side of hiring a decent stockbroker to help invest in stocks (they cost 1-2 thousand for a year unless you're going for an extremely proficient one and that's without you paying more for the investments). This set your ball rolling to end up elite pretty soon, lets you go back to whatever job you were doing or even lets you start a small business with a few months rent paid at a cheap apartment anywhere, especially if sharing. You even can call yourself a self-employed investor if they 100% won't allow you to rent while unemployed and it won't be an entire lie, in a legal sense hiring a stockbroker is the equivalent of a restaurant owner hiring a manager.
You need to get the ball rolling for your buy-and-sell business of some sort and eventually automate most of it and/or hire people to work for you.
Snowball, snowball and you're done.
This all assumes you don't begin with a wife/husband and children in which case I still would aim exactly at the 32k sweet spot.
Any more and you're risking it disappearing too much.
If 16k disappears there, some will care. If desperate stop there or even at the 8k.
