i would suggest you to keep your btc for long in your wallet, not use when you want, but have patience, maybe also use mining, or do some bets.
I'm worried that after November 16 bitcoin will fall. So is this really a good idea?
You can grow your bitcoins fast not only by growing them while your gambling or something else investing but you can also mine them that will be many times free and they will grow slowly to many coins. So just mining them is the easiest way.
