Bro be careful with your collateral requirements. I got burned by a green trusted sr. member because I thought it was safe. These hero accounts are bought, sold, and hacked all the time. I would recommend you always get collateral and a signed message from a staked wallet.
Not trying to sound noobish or anything, but Ive never had a reason to go through that so have never even bothered to understand it... How do you "Stake" a wallet? Just by signing a message from it? and if its an online wallet, (Local Bitcoins, Paxful, etc...), then wont the address any BTC is sent to going to be completely different from the address that would return the loan anyways?
Sorry if I am sounding a little "green", but on this one area I just cant figure out the benefit/security.. I'd like to though so I can have myself ready as I have found myself in need of a ridiculously low amount of btc for a few hours, but more on that one once the requirements are met
