I agree with you to use it for business, investment, and trading. You don't really have those nice things in life when you spend allin to getting it and at the back of your mind, you no longer have money for your other bills. I would rather take it for long term - use the 10btc for investment, trading, and business and just use portion of the profit to buy nice things in life.
We must not prioritize first on to thing that are less important on long term and we must secure and making some investments for long term so that we could able to earn profits with it. If you intend to spend it all at the first place the you would have a hard time especially when there are emergencies.
Exactly, spending them for buying things in fun, but that fun will be limited as once you spend your coins you will be left with nothing and you may regret in future when you see higher price.
