I'll have to take your word for it that there are hobby shops in the Netherlands. One of the big American dealers who has a large youtube channel currently resides in the Netherlands and he stated that the hobby was more or less non-existent there and that there were no hobby shops.
As for stating that the Netherlands is not a top 5 soccer mad country. Well, firstly what are you basing that on? Have you lived there? When you say mad what do you even mean? Mad as in passionate? Because if that's what you are stating that has absolutely no correlation to the hobby. Brazil is probably the 'maddest' soccer loving country in the world but half its population lives in abject poverty so not exactly fertile ground for the hobby. Soccer is absolutely the no.1 sport in the Netherlands. No other sport comes close. There is nothing else. Does the UK make your top 5? Rugby Union and League have a significant presence there. Soccer is their no1 sport but it's not the only sport - unlike the Netherlands.
Also, since you started off by taking the moral high ground by saying that you are just a collector and insinuating that I'm an 'investor' I'm going to assume that you have never sold a card in your entire life? That makes you a very rare species. I'm not an "investor' myself but I'm happy to flip some cards to offset the significant cost of collecting.
I'm curious as to the boxes you picked up? It would've been helpful if you had expanded a bit. Just stating you picked up a couple of boxes doesn't say much. Was it Panini XL Adrenalyn? Boxes of stickers? They've always had those - mostly in newsagents and supermarkets.
In regards to my comments about The Netherlands, I was speaking in terms of how mad their supporters are. I wouldn't even put them in the Top 10 to be honest and there are MANY countries that go unnoticed when it comes to football crazy fans. Brazil is definitely in the Top 5, but I wouldn't call them the 'maddest'.
In terms of national level football, the English fans are mental and definitely make my Top 5.
I didn't take the moral high ground at all, you have taken that the wrong way. I merely stated that I am a collector and not an investor, therefore I couldn't talk to that part. Nothing wrong with me saying that. I most certainly have sold cards but believe it or not, every single card I have ever sold has been below market price by a mile and sometimes even at a loss. I even sold a card today for $30 under what it's worth because I wanted to do them a favour. So please don't talk to me about "moral high ground" mate.
But you have gone off topic here. You were trying to make the point that basically the hobby is small and only in the UK does it have a chance of growing. My point was that I believe you are wrong and it is perfectly fine as a hobby and the interest is there. On an investment level, I can't speak to that as I stated earlier.
