I've been researching about what affect the price of bitcoins and I've come across this term that I cannot comprehend since English is not my first language am not really good at it. To quote and unquote what I read "the price is being bid up and up by trading bots and box accounts selling coins back and forth with no ownership change (wash or box trading) to drive the price up."
"Wash trading" is when one person (or company) trades with itself, to make the price seem higher. The text you're quoting suggests that a trader uses two different "bots" (computer software) to trade - right now the BTC/USD price is around $360, and this trader sets one of the bots to offer 1 BTC for $365. The other bot then accepts the offer (it buys the BTC), and the BTC/USD is now $365. At this point the trader hasn't gained or lost any money - they've paid an extra $5 for 1 BTC, but they paid it to themselves. Next, they try and sell more BTC for $365, but to a "real" trader. If they succeed, they've driven the price of BTC up and made a small profit.
I'm sure this does happen, but I'm not convinced it's that big a problem. There's
a great book about a stock trader from around 100 years ago. One of the pieces of advice he gives is "As I have said a thousand times, no manipulation can put stocks down and keep them down." In other words, it is possible to manipulate markets and change the price for a short time, but keeping the price at a "fake" level is much harder.
