BTCVDF is a Varnsdorf-based brand associated with Roman Korenec, covering Bitcoin education, community gatherings and consultations. It also offers Golden Gate sales representation and technical services. For a visitor, the useful distinction is whether they want to understand a topic, book tuition or discuss a product.
The person behind the brand is Roman Korenec. The website names BTCVDF s.r.o., company number 19302380, and gives the contact address Jarošova 1806 in Varnsdorf. Education, gatherings and services therefore share a name. These details help identify whom you are dealing with; they do not establish the quality of any particular advice. The abbreviation also needs context: BTCVDF names this local project, not the cryptographic function VDF found in a different technical setting. [1] [5]
A newcomer may start by asking why Bitcoin has value, then reach a more practical question: who can spend their money? The training offer connects Bitcoin’s technical workings, economics and wallet use. Self-custody means controlling the keys needed to spend, while also taking responsibility for a backup. Describing a specific need, such as understanding wallet recovery, therefore helps when arranging tuition. A list of topics alone cannot tell you what a participant will actually learn to do. [1]
The Media section contains opening remarks for the BTCVDF 2023 conference and a recording of the gathering Jak nezchudnout, roughly “How not to become poorer.” These offer a way into the topics before attending in person. Dates matter in an archive: an older economic commentary arose in different circumstances and may not describe today. A recording’s label is not a promise of another edition, either. An old recording should therefore not be read as an invitation to a conference in 2026. [2]
An invitation in Hlas severu 7/2024, page 8, shows the local setting. BTCVDF and Hosana church invited people to discuss financial literacy and investing on 19.4.2024 at 17:00 in Varnsdorf’s Hosana centre, in the hall one floor above the entrance level. It started with the everyday concern of not becoming poorer and was to cover how the financial system works and the risks of investing. It is a concrete trace of local public education, although an invitation does not reveal attendance or the venue of the next meeting. [3]
A blog post dated 5.2.2025 records another link to the Czech community. It invited readers to a Jednadvacet meetup on 7.2.2025, describing opportunities to get to know one another, exchange ideas and connect Czech bitcoiners. A meetup is simply a gathering around a shared interest; conversation around a table may matter as much as a talk. The invitation’s reference to a first meeting does not mean that the whole Jednadvacet network began then. A future visit needs a new invitation, rather than reliance on an old date. [4]
The offer combines different commercial relationships. The website describes support linked to Golden Gate products as free, while listing personal consultations and tuition at 2500 CZK per hour plus VAT, or value-added tax. Corporate training is priced according to scope. Free support does not make the product itself cost-free: its price, fees and contract need separate consideration, and the rate should be confirmed before booking. Sales representation is also different from an independent comparison of the whole market. Attending a discussion does not commit you to buying anything. [1]
Alongside tuition, the site offers electrical work, Loxone smart-home installations and photovoltaic projects, with the option to pay in bitcoin. This gives a customer a tangible example: bitcoin can pay for work, rather than just be the subject of a talk. The offer does not specify whether payment would be on-chain, recorded directly in Bitcoin’s chain, or through Lightning, a network using payment channels. The payment method therefore needs agreement beforehand. An available payment option does not tell us how many payments have taken place. [1]
The contact page is for arranging an in-person or online meeting with an agreed topic and time. Its form asks for a name or company, email, category and message. A useful enquiry might say: I want to understand the difference between a wallet I control and an account with a provider. That makes the help being sought, and the agreement needed, clearer. Sending a question does not itself buy Bitcoin; it is also not an anonymous route, since contact details are supplied. [5]
For the clearest picture, read this entry together with Jednadvacet, Bitcoin, Self-custody, Lightning Network, Merchant Adoption. The reverse links also lead from Jednadvacet.
