lending? are you seriously? I don't think this is a safety measure. there have been too many great losses from Bitcoinnect and most of the other bad businesses. This is really not a good advice. Instead of having a lot of capital, we should do a mining or staking work. It's one of the most profitable ways out of the way you set.
You didn't really get the aspect of lending he is coming from. Yes Lending is very risky because you are lending someone who you don't know his locality or anything else about him and you are expected to sleep while making money when the person can decide to deactivate or even hibernate while the collateral he put forward might be worthless. But what he is saying is that you can transfer the risk to someone else which are the services he has provided. All you have to do is to put your funds there while they handle the rest.
Another one OP didn't mention is some sites pays you daily interest for keeping your funds there. I know about Yobit but this also comes with its own risk because should the site crash, there is nothing that can be done.
