I have a lot of gold and always making more and i have bunch of 80 lvl characters. I'm wondering is it better to make gold and sell for coins and repeat, or invest that gold in characters to buy 280%, 3-4 expensive BOE's, 2 professions and give character 10k gold and sell him ?
For my experience both variants is good, but gold much faster.
Also there classes that you can sell forever... People just dont want nor play them, nor buy them.
So my advice is simple - make gold, sell gold, buy what to want.
Sell gold because selling character is 10x harder unless you stumble upon someone buying exactly what you have, just putting character on sale isnt enough, you probably need to spam global and discords to sell it. Also if you gonna throw 10k gold, bunch of expensive boes, 2 professions, you are still looking at 30 coins character and my opinion its not worth it and you would probably get more coins from selling gold
