First of all I remember BTCjam, and that was a bitcoin lending platform. Their problem was that they where truly at the bottom of the lending chain. The last place desperate people with awful credit scores would go. That is hardly relatable to this project.
I mean. Welltrado is not even a P2P lending platform. It is a marketplace connecting all the platforms together into an ecosystem.
I have dabbled alot with these types of investments, I have only experienced that a loan didn't pay back, when I got to greedy and was part of loan with 48% return rate. Luckily I didn't invest much in that. Because due diligence, and spreading your money across many loans. Which is exactly what Welltrado.io promises to do
