I've heard good things about monero from a friend. This is not an attack on monero, rather a reflection on the general tone of the message.
Monero is so obscure the IRS has put out a million dollar bounty to trace it, unlike any other crypto even btc lol
It's much less easy to convert it to something you can actually spend. Even if you can get it to a buyer, they'll always offer you less than you expect/want.

Gold sells at about 1% less than the current market price of the gold content of your item which I find fair. It might be easier here in Antwerp than in other places to deal with gold because it's kind of a gold trading hub. You can basically show unannounced (I suggest going by bike rather than by car because there is little street parking) and trade your gold for cash at the -1% rate, obviously if you get to the million euros range it's going to be a bit different, but for a few tens of thousands it's business as usual. And it's not like it's a difficult place to reach from anywhere else in the EU.
