As mentioned above, cryptocurrency relies on peer-to-peer networks, which is best defined for the laymen's of us (which, at this point, is most of us). The peer-to-peer network, a non-hierarchical network, is a computer network of interconnected nodes that do not communicate according to the client-server model.
This means that different computers are not assigned specific roles in communication and that no nodes have any special privileges over the others, but that all nodes in the network can act in all roles (be a peer). So, in fact, we all use peer to peer networks in some way, or have in the past, it is just understanding their vital application to blockchain that helps.
What is money?
In the EU region, the euro (EUR) is the legal tender. According to the legal requirements, wages/remuneration have to be calculated and paid in Euro. The reason for this is that the legislator wants to ensure that the employee can actually dispose of his wages. An exception to this is only possible if the employee works abroad for more than one month, with it is possible to pay the salary in another currency.
However, this is understood as the currency that is legal tender in the respective country. Although it is indeed termed Crypto "currency", it is not an official currency. They are rather to be classified as a reference to reality. A benefit refers to any donation of an employer to an employee that is a monetary benefit but is not provided in cash. This is regulated in the Industrial Code and allows employers to pay their employees in kind.
However, this only works if the employee agrees. The remuneration can not be paid in full, but only partially in kind. At least the part of the salary that can not be paid out has to be paid out in cash, that is, euros.
Since cryptocurrencies can fluctuate significantly in value, a parallel is drawn to equities. The share of shares in the employee's total remuneration has not yet been finally clarified. According to the legal concept of a decision of the Federal Labor Court would probably be 25-30% admissible and also the remaining portion may not fall below the minimum wage. This limit is probably to accept for cryptocurrencies. It is intended to prevent that too much of the salary, in the end, could be worthless.
It makes sense here, too, to consider remaining within the tax exemption limit for benefits in kind. This is at 44 euros per month. If the value in kind exceeds this limit, the entire value is fully taxed by the employee. According to a new ECJ ruling, the conversion of Euro into cryptocurrencies is in any case VAT-exempt. Should remain below the 44-euro limit, of course, only cryptocurrencies basic tax be paid.
