I dont really give this advice but looking at your assets you can consider this one if you try to get good sources for you. You can go and lend your money in the BTC form or other altcoins whichever is easy for you. But remember that lending is very risky business BUT very very profitable in the long run as they have heavy interest rates. You can earn huge $$$ with this method. But you must have very very legit source and be sure to get the collateral security for yourself.
