Don't say people didn't warn you.
While nothing is guaranteed, this is a very shortsighted view and plain ignorant way to look at things.
"doing it themselves"
...Is not an option period. Traders need speed and liquidity. And lenders need a intermediary to protect their loan with margin requirements and position liquidations if necessary.
Bitfinex simply provides the platform for doing that.
The reason for such high loan rates right now is because there is high demand and few loans. As soon as more loans enter the system then the opportunity decreases.
As with all investments, those who recognize value first get the biggest advantage.
There's no way this opportunity will continue forever.
So why not get a real loan in the real world and then lend it out on Bitfinex? You'd make a shedload of cash, especially if you kept quiet about it keeping the interest rate high since d > s?
Right? I mean that's what I would do if I didn't believe this site would eventuallt make off with your cash
That is a very doable arbitrage play right now. Do it.
