I politely disagree! At Btcpop.co lending can happen with 100% or more collateral held in either altcoins or P2P shares on Btcpop.
In regards to reputation based borrowing yes this if done improperly can be disastrous, however online reputation systems are effective and efficient when implemented properly.
Building on online reputation to the point where you can borrow substantial BTC at Btcpop is not quick, cheap, or easy. Making the incentives very poor to loose that reputation for possible future loans. Also verification and a community of scammer hunters makes running even less appealing or beneficial.
When I look at any investment structure, I ask, who has the most to gain and who has the least at risk? Does btcpop.co supplement the collateral so all loans are 100% refundable? If not, you force the lender to take extra risk at the cost to the profit of the company. I don't like these systems at all, especially if they don't have multisig to lock in contractual agreements. It's too early to do loans the proper way. Hence, I recommend people to not lend, but keep making money just buying and holding btc. But lending... You give up your keys, you give up your btc.
