Coinexchange.io question!!!

[Lm2e4]

I'm new to this exchanger so I haven't use it before. And when I almost try to deposit some Ether on it, I suddenly got afraid on this notice;



So here is the question, for you guys who've done exchanging on this exchanger, what does the internal transactions actually means? And what is the difference between internal and normal transactions?

And can I also send some Ether on it using shapeshift as a medium between Bitcoin and Ethereum?

Thank you for who might answer this question clearly!!
