What is the difference between open.btc, trade.btc and bitBTC?

bitBTC - you.

True, but I would say:
bitBTC - Bitshares blockchain.

If you send your BTC to poloniex, then the BTC on your poloniex account is actuall poloniex.BTC, instead of real BTC. Same here.

They are issued by different parties. OPEN.BTC - openledger, TRADE.BTC - blocktrades, bitBTC - you.
