Welcome to another new crypto news summary. Read on to find out all the important news and events within the world of cryptocurrency from last week.

Bitcoin mining device costs just €2,80

Bitmaker, the company behind a revolutionary Bitcoin (BTC) mining computer, has managed to produce a mining computer for as little as $3, or €2,80, each. Although the yield of this compact mining computer is not extraordinarily high, its arrival marks a major turning point in the Bitcoin mining industry. This is because this industry has been suffering from a mining exclusivity problem for quite some time.

The introduction of the small and affordable mining computers is meant to be a powerful counteraction to the "secret and exclusive" atmosphere currently surrounding bitcoin mining. Bitmaker's machines are fully in line with the fundamental idea behind Bitcoin: "open-source, transparent and accessible to all".

PostNL takes another step into the world of crypto

About a year ago, the Dutch postal office PostNL enthusiastically made its entry into the world of cryptocurrency by launching their very first collection of NFT crypto stamps. This 'NL crypto stamp' quickly caused excitement within the Dutch crypto and collecting community, and the release was a great success. It was so overwhelming that PostNL is now ready to present a second collection of NFTs.

As a follow-up to last year's collection, the launch of the new crypto stamps is accompanied by a challenging game called: 'Hack the crypto wallet'. The lucky and clever participant will have a chance to win an exceptional prize: a gold crypto stamp. Made of 20 grams of pure gold, worth more than €1,100 when announced.

Every week, participants will receive a clue that will bring them step by step closer to the correct password for the crypto wallet. This process takes four weeks. The one who enters the correct password first wins the sought-after gold crypto stamp.
