The number 25, as I brought up forn<\/a>, has a magical appearance.<\/p>\n

2025 is the first perfect square number year since 1936, and thus also the first year to be a product of two squares since then. 2025 = 45² = 9² × 5².<\/p>\n

Coming back to 45², Donald Trump, the 45th president of the USA, will start his 2nd term in 2025 as the 47th president. 45 + 2 = 47.<\/p>\n

2 + 0 + 2 + 5 = 9, which is the number of completion, the hightide of the material experience and a bridge to the spiritual. 9 holds the wisdom of 1 thru 8.<\/p>\n

Likewise, 2025 is the sum of all cubes: 1³ + 2³ + ‹...› + 9³ = 2025.<\/p>\n

Putting aside the issue of centralisation<\/a>, cash is quite a good means-of-exchange. Transactions are private by default, work without digital technology, and do not require intermediaries.<\/p>\n

This latter point is as important as the two former ones. Most banks have a transaction fee that nearly<\/a> always goes unseen by the customer. Using cards instead of cash lets parasitic intermediaries amass money originally belonging to productive men and their families:<\/p>\n

y<\/i> = 100% × (100% − 2%)n<\/i><\/sup>, n<\/i> being the number of card transactions<\/div>\n<\/div>\n

The banking cartel dreams of a cashless society because it will enable free reign over transaction fees, and thus the acceleration of the transfer of wealth. The Italian bank-terminal mandate and cash-transaction cap must be abolished.<\/p>\n

Avoid banks whenever you can. If withdrawing cash, use the ATM twice to drive up the statistics: for example, withdraw 100 € two times instead of 200 € at once.<\/p>\n", "summary": "Most banks have a transaction fee that nearly always goes unseen by the customer", "date_published": "2023-03-02T17:47:08+02:00", "date_modified": "2024-11-02T15:36:47+02:00", "tags": [ "Italy", "maths", "might", "scams", "wealthlore" ], "image": "https:\/\/robert.uber.space\/blog\/pictures\/bank-fees.png", "_date_published_rfc2822": "Thu, 02 Mar 2023 17:47:08 +0200", "_rss_guid_is_permalink": "false", "_rss_guid": "851", "_e2_data": { "is_favourite": false, "links_required": [], "og_images": [ "https:\/\/robert.uber.space\/blog\/pictures\/bank-fees.png" ] } }, { "id": "772", "url": "https:\/\/robert.uber.space\/blog\/all\/luck\/", "title": "Luck", "content_html": "

Luck does not exist. Quoting Ron Swanson, luck is a concept invented by the weak to explain their failures.<\/p>\n

There is, however, a cause for every effect, and an effect for every cause.<\/p>\n

What is referred to as beginner’s luck<\/i> is an invitation to continue the journey. I won my first-ever game of Go despite playing against a world champion doing his best.<\/p>\n
