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.
Bitconnect and her likes were just Ponzi, scams disguise as leading platforms. This isn't what the OP is referring to, read the OP again and you'll understand he isn't asking you to invest in any worthless project advertising themselves as lending coins. Instead, there are platform out there were you can lend out your bitcoin and selective altcoins to loan seekers and in cases of loan default, you get compensated from the site with the collateral deposited by the loan seeker before the transaction was initiated. Before you patronize any of this platform, do some research to make sure you aren't patronizing a scam or shady platform.
You can also successfully used the forum as a host platform to offer this lending service but be cautious of those you deal with and it's preferable to ask for redeemable collateral (minimum 120%) preferable well established cryptocurrency to unattract scammers hoping to leverage on a non collateral loan to scam.
