I am creating iOS application where local carpenters can sell their furniture in my app.
My business model would be based on a small fee per transaction (let's say 0.001% + 1$ per sale). Is it possible with PayPal (how)?
If not - are there any alternatives?
Not related to coding, but business-wise, .001% seems like smaller than you mean for it to be. A better amount would be something like 5%. If your app succeeded beyond your wildest dreams and you started doing $1,000,000,000 a year in sales, .001% of that would net you $10,000.

I'm trying to find an "Exchange/trading platform" with the following conditions
I must be able to purchase currencies (fiat or crypto) and not need to return back to the base currency. I do not wish to open and close positions. I plan to only take, never make. - Is there a name for this?
The commission needs to be as low as possible preferably less than 0.1% per trade (I want to high-frequency trade)
I'm after API access for the High-frequency trading.
I'm after a large grid/table (every currency into every other currency) for example:
Ideally, 9+ currencies. - I have made this in excel using modified data from https://www.exchangerates.org.uk/currency/currency-exchange-rates-table.html
If all of these exist on a single website, that would be wonderful!
Thank you in advance for any and all help.

For a long time my adwords account was working with NIS currency (while 1USD = 3.5NIS). I've decided to transfer my account to USD currency, for this I've opened a new account and copied all campaigns.
I've noticed something very bizarre in my new USD account. Keywords which were placed in the first page with NIS currency now require a much higher bid. For example, a keyword had a 0.82NIS bid (0.24 USD) and had avg. position of 2.8 now requires 1.31$ according to google to enter the first page.
How is it possible?
Thanks
I'd guess that the most important factor is that your new account has no CTR history, meaning that your quality score tends to be much lower than in your old account.
This in turn leads to higher first page bid estimates.
Your Google account manager might be able to change the currency of your old account if you're a big spender an important customer. That way, your bids should stay pretty much the same.
Is it is possible to make users pay for digital points so that they can use them for real-world services outside of the app?
Take for example 'Uber', assuming we have the same model, can users purchase 'bundles' of 'points' and then use these points to order a taxi service?
Will this be allowed on the app store?
This is basically the "digital wallet" problem. All kinds of issues exist, from security, to convincing vendors to accept it, to convincing customers to trust and use it, to figuring out how you're going to take a fair profit out of it..
Frankly, Apple has claimed to be working in this space themselves, as are the credit card companies. Given your question, I have to assume you have nowhere near the resources they can afford to spend on this effort, and their efforts are still vaporware.
If you really have a way to make this work, I suspect you could sell it to one of them for a few million. If you just have the idea... well, it's premature to try to guess whether Apple would try to lock you out or not, and only they can answer that question in any case.
Is it possible to generate a single promo code which can be used multiple times by multiple users, or is there a one-to-one mapping between codes and specific users?
What I'd like to do is publicly post a single code anyone can use.
Is this possible?
The promo codes are one use only. The person using it is buying your app but without paying any money to Apple. You could lower the price of your app to free for a limited time if you wanted.
We have a web app that among other things, allow users to leave a cash balance on their account (which can be cashed out anytime or used to purchase items on the site). Users can withdraw and deposit funds to their account anytime. It was never intended for it, but we now have users who leave large sums on their account and they're now requesting that we provide some interest on their account balance which is totally reasonable. Problem is we have no idea how to calculate interest on an account where users can withdraw and deposit funds anytime, but all the banks obviously do it so I was wondering if there's a standard way (or ruby gem) to calculate interest. Any pointers or help is greatly appreciated.
The db table setup is pretty simple.
User has one Account
Accounts(user_id, balance)
Account has many activities
Activities(account_id, type, amount, description, created_at)
Where type can be either "Deposit" or "Withdrawal".
For the answer on what interest calculation to use I agree with Ray Toal that you are going to have to ask your client what interest calculation to use and what their payment scheme is like.
Usually speaking, financial institutions that offer interest on a chequing account are calculated with compounding interest calculated daily [at the close?] of each business day and paid monthly at the end of each month by a deposit directly into the account.
Notably, banks and other financial institutions will tell their clients the interest rate on a yearly basis (APR) and not the interest rate per-day. It is an elementary mistake that I have made in the past.
Take a look at the Exonio gem: https://github.com/Noverde/exonio.
This gem implements some of the Excel financial formulas, including the Interest calculation that you are asking for.
From their docs:
What is the interest part of a payment in the 8th period (i.e., 8th
month), having a $5,000 loan to be paid in 2 years at an annual
interest rate of 7.5%?
Exonio.ipmt(0.075 / 12, 8, 12 * 2, 5_000.00) # ==> -22.612926783996798
So, in the 8th payment, $22.61 are the interest part.
