OP could be scammed when the buyer just denies having received any funds. since btc in no legal tender, will blockchain info work as a prove of payment? Have you checked this with your lawyer?
nonsense I wrote here. Sorry guys. I knew what I wanted to say, didn't come out that way. It made sense the moment I thought it.
So, the contract is signed, funds are sent afterwards vs. contract signed, no funds sent. Will the blockchain be sufficient as evidence that no payment was made?
In a court in Germany? Doubt it.
Also can you even pay for a house with BTC in Germany?
Sure why not:
http://www.bafin.de/SharedDocs/Veroeffentlichungen/DE/Merkblatt/mb_111222_zag.htmlUnits of Value intended to function as currency that can be exchanged against real benefits, goods or services or that f.e. Bitcoin, can be created in computer networks ar not classified as E-Money, even if they serve the same economical Funktions as E-Money. [snip]
A permission to create and use this Units of Value as currency is not required. If this Units become a commercial subject themselves the business has to qualify as Bank account as for § 1 Abs. 1 Satz 2 Nrn. 4 or 10 KWG or Financial Service Provider as for § 1 Abs. 1a Satz 2 Nrn. 1 - 4 KWG and operates under reservation of § 32 Abs. 1 KWG
It's allowed to accept BTC as currency for anything.
I also strongly Belive, that the Blockchain would be sufficient proof of payment for a court in Germany.
Just make sure the receiving BTC address is in the contract.
