I've stopped reinvesting, although to be fair I had stopped reinvesting for about the past year. There were really a combination of things that did it for me:
1) The tax inefficiency on a taxable account is a killer.
2) The lack of liquidity prevents me from ever investing in size, i.e. >10% of my net worth. Neither Prosper nor LC have taken tangible steps to create a real secondary market, i.e. not Folfio, which is discouraging. I don't want to have so much tied up in an illiquid asset.
3) The rates LC offered most of last year were not that attractive for C and higher grades. A-B were adequately priced but not that interesting to me in terms of total return.
4) Lack of BRV is a long term concern for me, even though LC will remain solvent for at least the next 4-5 years in my view.
5) LC hasn't proven that the business model is that viable. Even in 1Q16, they were only minimally profitable. If originations go down this quarter then LC is probably back in the red.
The scandal last week was the final straw for me. The whole P2P idea was interesting but frankly I'm not interested in taking a ton of risk for maybe a few hundred extra bps in return (at best), especially since almost all that return is given up due to the tax inefficiency. I do think its an attractive asset class for institutional investors though.
