I had the same problem untill I saw Bitmex a while ago. I tried it, they were legit and payd out. I liked it
for the "trollbox" aswell. I used to trade poloniex a lot, the Development was really bad on their platform.
Bitmex might have nothing to do with poloniex, but its just as profitable (now a lot more profitable actually).
The costs to open a contract are really low on bitmex. See it like this:
You have 1K usd. You see that the price of btc broke 7k and u want to speculate on an upwards movement to 7.7k. You buy 1 BTC in contracts ( 7000 USD contracts / 7x leverage ). Do not even worry about the fee's here. The BTC P-Swap contracts (first BTC option on bitmex trading) has a fee per 8 hours but never ends. The second option ends december 2017 but has a 1 time fee only and IMO is better for trading waves / paterns. If the price goes to 7.7K you will get 700k profit which is 70% of your Equitity so your ROE would be 70%. The total increase in BTC value however is only 10%.
Ofcourse the same counts on downwards movements. I use bitmex mostly on breakouts and am very carefull with using to much leverage. Using more than 1 Bitmex account also helps to reduce risk
sometimes you get tempted to overbuy positions.Hope you guys agree that Bitmex is the place to trade with low investment _+ decent trading skills.
