Is bitvavo popular there in your country? Honestly, I have never heard anything from that exchange but if you're fine using them and you have proved them to be legit, all on you.
And about such amounts, I think you should be patient and don't do the 2 times 10k deposit because even if they say so that it's fine. That amount is likely a lot for a transaction.
I've read before that what if you do like $1k or $2k per transaction as that won't trigger them from asking why is that amount being made and transferred by you.
Quite a few people use it but none of them have been visited by a tax agent. I expect this to happen soon, as part of the fight from the government. These people have a false sense of security and banks are getting nervous about losing liquidity.
I see a plan to avoid these hawks ripping me to pieces:
I spread my initial 15k investment amongst 3 people:
- Me
- My wife (I transfer 5k to her now. Banks will see this, but she is the real owner)
- My father (I give him 5k later)
When the money is paid, I make my mother in law (who lives outside of the EU and is almost 80 years old) go through KYC.
We manage her account though. There was never a bank transfer (fiat to BTC) in her name, so banks in Brazil will not expect anything. There will only be a crypto transaction of our 3 accounts here, to hers. She doesn't live here so our government can not tax her.
When the tax hawks come for me, I say that all BTC has been transfered to my non EU family member as a donation. Because BTC taxes in her country (Brazil) are much friendlier. I can also prove this with my transaction history. This is like someone trying to take my money at gunpoint, and then realizing that there is nothing to steal. I don't think they will contact the authorities in Brazil because there's nothing in it for themselves.
However with my mother in law at 78 years old.. What happens if she passes away with 500k euros worth of BTC on her name?
I wonder if it ever gets to a point where we actively need her fingerprint or live camera footage to transfer her BTC holdings in 2035, for example
