Lending business is very risky but if you can able to handle the risk then it should be fine but always ask for strong collateral anytime you do give loans. This business is very profitable on longer runs when it goes fine .
Never invest even a single penny on cloud mining sites because most of them are just total scam.Trading is the most common way that most people would select when it terms on doubling your money but still depending on how you gonna trade well.
