is a Cryptocurrency Exchange.
It has Margins, and multiple coins. Low fees.
I have no financial connection. Just a user.
On Poloniex you can trade bitcoin and other coins you aleady own. Most of the coins trade based on the price of bitcoin, so generally when bitcoin goes up they go down, but there are no rules. It is the wild west, but this is a reliable platform. It has Stop Limit trades and Margins. You can lend people coins to use for margins and make interest. Keep and eye on the Info box, and ignore the Trolls. It's fun. Buy low, Sell high, and diversify. Very small trading cost. http://www.cryptosecond.com
is my personal site with links and info on how to buy, mine, and get free coins.
Margin Trading and Lending Information: https://poloniex.com/support/aboutMarginTrading/
If 1 bitcoin equals $1000 and you loan at .01% daily interest
You get .0001 a day or about 10 cents
If you can keep loaning at that rate for a year
You get .0365 btc a year. That is 36.50
The current lowest ROI is .0176 which would make .063 or 63 dollars.
Indiviuals cannot borrow from the lending pool without collateral.
I am not endorsing any coin nor guarenteeing success.
