Why only use a thousand dollars to open a copy trade?

My approach is a quantitative hedging strategy. If I use a lot, many brothers won't be able to get on board, and getting on board = liquidation.

So I use $1000 for this, which means as long as brothers have more than $500, they are safe. The copy trade has been running steadily for 81 days, and the dark pool has been running for one year and two months.
