I'm not going to for several reasons:
1) Even though I have a Fidelity brokerage, they are requiring me to open a second brokerage account to even show interest.
2) I have no idea what the minimum investment is. I wouldn't mind putting 2.5-5k into it, but if the minimum is any higher than that, forget it.
3) Very speculative and risky. Yes, you could get a 40% pop on day one, and you might be able to sell it for mad profits...or it could drop 30% in day one and you're only consolation is that it's a tax deduction.
4) I just don't like Lending Club. I started investing with them in 2010, but quickly decided that was a bad call. They don't let people in my state invest, so we're stuck buying them through their trading network. That makes the time investment to keep invested very large. Not to mention that all of the good loans get snapped up, but because their trading platform is awful, you can't tell what's been bought yet. What this means is that I would spend a few hours and pull the trigger on 30 loans, but I'd only actually buy 5-10 at the end of the day.
The only reason I like LendingClub is because it seems like a great business model. They have no risk from loans defaulting other than potentially pissed investors. They only make their money off investor fees and maybe origination fees? I got a little upset when I realized that they took 1% of every payment to the investor. When you're investing in $25 chunks for 5 year time frames, what this means is that a common payment to me would be $0.10 interest and $0.40 principle. They took 1% of the interest (rounded up of course) which means I paid them $0.01. That's great, till you realize that they just took 10% of my profit. The effect gets worse the smaller the interest part of the payment gets.
