Thanks for your input. As I said, KYC doesn't bother me too much, I've decided to be transparant with banks and tax authorities through this whole sell operation. Sounds like the same questions my bank asks me on a regular basis.

OTC is something I didn't even think about, didn't really know that was a thing nowadays honestly. Gonna look into that some more, thank you very much!

Not interested in signature campaigns, and didn't feel like waking up my old account that has been sleeping for 5 years now for some reason

Thank you all for your answers. I'm not really worried about KYC, more so if i.e. Coinbase would accept my explainations. My bank will most likely go nuts when a few hundred thousand euros arrive from a foreign bank, but rather than having to fight 2 battles, I'd prefer to just fight one.

I'll keep looking into the P2P options as well, but that might be more difficult to explain to authorities, due to the amount of money and extremely strict AML laws.

Also, consolidating my transactions is probably a very good idea. Didn't even think about that. I'm using my old legacy addresses as well. Thanks for the tip!

Not very familiar with the modern p2p exchanges tbh, looked around a bit and that might work if I find a buyer willing to buy a few bitcoins at once within my country. Gonna look into that option a bit more, thank you for the advice!


Does anyone else have any experience with centralized exchanges and what they can accept as "Proof of funds"?

Hello, long time bitcoiner and HODL:r here. I'm thinking about "cashing out", some or all of my Bitcoins if the price goes higher.

Decided that Coinbase seems to be pretty reliable, so I thinking about using them.

My problem is however that I've never bought any of my Bitcoins. I got all of them from faucets, signature campaigns on here, translating websites, doing online tasks (like surveys), mining (back when CPU-mining actually worked), some trading between BTC and LTC, and so on. Roughly a thousand transactions between 2012 and 2015, when I stopped aquiring.

So when the day comes and I'll wanna sell (a few bitcoins), I imagine that Coinbase will ask where and how I got them.
The blockchain is obviously public to support my  story, and I have access to my old Bitcointalk account (didn't wanna use that account to create this thread however), but for a lot of the bitcoin I recieved back then I have no documentation (since back in 2012 for example, I didn't really see the need to document where every 0.01 BTC transaction came from).

Does anyone know Coinbase accept such anecdotal evidence? Obviously I can go into more detail when this actaully happens, but I wanna know if it's game over from the start and not even worth bothering with Coinbase or other exchanges.

I imagine I'm not the only one who is in this situation and wonder what to do to make it "by the book"? Would be quite sad to transfer my bitcoins, get my account locked and lose access to pretty much life changing money after all these years of hodling.

Thank you in advance!
