a few months ago, trollnetwork.com whas for a hobby then 2th domain whas privemagazine.nl wich i recently sold for €75 thaatss how it all started for me
I bought my first name in 2001, (much older than 12) The first time I paid the slightest bit of attention was in 1997. A friend of mine owned a bunch of generic one word .coms. He said someday they would be worth a lot of money, but I hadn't a clue back then.
2012, if I can recollect. It was for a personal blog. Only around October 2016, when I sold that blog, did I realise that there is something called as Domain Trade!!!
2012, bought few domains for sell without even the slightest understanding of sales or domains
These were seo-promotion.biz, world-games.org and two IDN names. When came expire date I deleted all names and thought - it's a bad bad business and I cannot make money on it.
A typical mistake of a person who is looking for the cause of problems in something, but not in himself (in this case - the lack of market understanding, which names pick up, who is my end user etc).
