I only trade on bittrex and don't see anything like that there, I heard polo has margin, is it polo?
thanks again
To be honest I don't know the answer to either of your questions. I've never been interested in doing either in crypto. Way too dangerous. Crypto is way too manipulated. I only buy what I think makes a good long term investment and I only sell long positions when I think long term gains can be brought forward and realized today instead of sometime in the future (that being said, I have been playing around "making a market" in one coin on a smaller exchange, but nothing serious). But from what I understand, Poloniex, you know, that highly manipulative exchange with the troll box on the right of it main exchange window, has margin trading and also lends coins that can be shorted. As I said, the risk is extreme, not just with the markets themselves, but also with the people/exchange you'd be dealing with, and I DON'T RECOMMEND it. What I'm sharing here is for short term fun and perhaps a little more long term gain.
Talking about that short term fun and long term gain, we did gain some insight into short interest in DGB last night when 103 was broken: it was almost anticlimactic, a non-event, so to speak, which either shows that there is next to zero short interest, or zero (if it is the case that DGB can't be shorted in the first place . . . as I said, I don't know . . . someone would have to check with Poloniex). That aside, for the long side of things, the 2 hour chart long from 82 was confirmed on that break. (edit: on closer inspection, it looks like 104 was sold into, not too heavily, but, well, lets say with a little gusto - the rejection was visable on the 5 minute chart . . . a blip on the long term chart though.) Next target 128-130.
Edit: out of curiosity I clicked on the Margin Trading tab (like I said, I was never interested before, so why go there?) and it looks like there is a very reduced number of coins that can be traded on margin . . . and I imagine that it'll be the same list for shortables as well.
