Sorry bud but every decent exchange is asking everybody to upload their ID these days... Binance doesn't but cash outs are limited and I'm not sure if they allow margin trading for XLM or any other crypto.
I was most looking for market with no ID needed and there could be limits (1-2 BTC daily is ok) with shorts:
a) binance doesn't have margin market
b) poloniex have XLM shorts but they want ID
c) bitmex have shorts without sending ID but they delisted XLM :/
d) bitfinex have shorts without sending ID with limits but there is no XLM shorts
e) kraken doesn't have XLM shorts
