what I do if you give me 10 bitcoin? if you really give me 10 bitcoin then I will use bitcoin it for I use to invest in bitcoin or altcoin trading and bitcoin mining

if you gave me 10 btc, I think I would use part of it to trade altcoins to make some profit, as less than ten bitcoins is enough amount  to start trading,  so even if I go through losses at initial stage then also I can recover it in future.

I don't prefer to suggest lending for it is really risky and since we are in digital world this is the toughest type of business that you are going to make. Because you don't have assurance that your borrower will pay accordingly regardless his status or trust records. Because even the most trusted people are making some trouble because of it. I think it is better if you are going to make real life lending through your neighbors and known people.

You are right, lending does not work well in online, but with 10 BTC you can already establish a lending business in a physical world if that is your expertise and you know well the market, with lending business the ROI is fast if you can manage it properly, at least you are safe as you know your borrower.

any business can very well be very risky if you are not careful about it.
lending is no different. there are some risks but also at the same time there are a lot of ways to manage these risks and reduce them to an accepteble amount. for example you can do this by taking a valid collateral which you can sell easily on the market.
