Today, I sold one of my gear, and I looked at my spreadsheet to gauge how much I spent on audio gears since I started this hobby. If I sell my all gears at market prices, my net spent would be around $2800. It's been around 33 months since I started this hobby, I spent $1,000 per year on average for audio consumption. While it looks neither astronomical nor unsustainable, I feel like I am piling more losses as I buy and sell mar gears repeatedly. I thought it is similar to stock trades. People buy and sell to make greater profits, but in reality, they find themselves piling more losses with more trades. It might be better strategy just buy and hold until I find a really good opportunity. Just my 2 cents.
