    MoneyCSV

    MoneyCSV

    Personal finance program based on CSV text files (no closed database)

    This personal finance program allows you track all personal accounts including investment accounts. Money CSV provides reoccurring bills, budget tracking, report generation, net worth tracking and custom transaction import rules. The program supports importing of downloaded transaction files (OFX, QFX and QIF). Money CSV supports stock price updates if you get a key for the Yahoo Finance (YH Finance) API from RapidAPI.com. The intro level API key is free, and you get 500 downloads per month of all your stocks, which is plenty of downloads as one typically just updates once a day. The main advantage of this Money CSV is that all account transactions are stored in CSV text files rather than a hidden database format. This means that your financial data is always stored locally (or on your own cloud) and your financial data is always accessible as the data is stored in human readable text files.

    chaOS41

    A cryptocurrency like Bitcoin improved upon with reality binding.

    There is a reason this project holds no code. chaOS41 is a cryptocurrency with reality binding. A given value of money was paid for a surface area the size of a flower pot. It was out of proportion. The chaoOS41 currency corrects that. It binds its value to reality. Its unit value is a ratio between money and land area.. When that ratio normalizes, the currency becomes available to the public. 1 more developer is wanted. For that you need inside access, which means the access protocol is made public now. It is also the open-source cryptographic protocol. Type in a formatted string as "beacon" and a number. Repeat. When the identical string is produced, prepare. When the identical string repeats, a name is added. This signals that the next line of text you type, is registered. Hint: include a URL.End of protocol. Valid beacon digits are 250, 1024, 2048, 4096, 8192, 16384, 32768 and up.
