I've kept the coin in a closed coin box for all these years.
Unfortunately I do not have the hologram anymore. Even if I did, I probably wouldn't include it. My real identity can easily be solved so I don't want my bitcoins or trades with bitcoins to be tracked. But that's just an excuse, I got rid of the hologram when I emptied the coin.
Well with what,, 14? 25BTC opened this year, unless you used a mixer I think it would be pretty easy for someone like Quickseller to figure out which one you owned. Maybe a little harder if you opened it last year as there were 82? opened in 2017 But I doubt if you opened it last year and held onto it so long but who knows
