That is a good choice.I would also like to invest this amount in mining bitcoins.Alt mining,although cheaper than bitcoin,is more riskier.Since electricity is less expensive in my area I would like to give bitcoin mining a shot

10 BTC cost roughly 6800$ now. You can now start a business with this balance. If you will ask me, I will start my real time business maybe online or not. In case I still didn't want to start my business yet, I will use it on trading sites or at gambling sites to make it grow more. But I prefer that dont put it on Ponzi's or HYIP sites because that's too risky. But be sure that you know how to earn money on trading sites. Because if you don't know, maybe your 10 BTC will make it Disappear in no time.

If you give me 10 bitcoins, i believe it is impossible, why you give me 10 bitcoin, i think you want ask us that you have 10 Btc, and you wana ask what will you do with your bitcoins. the Answer is now you should save it because now halving effect in progress price may go high and save your bitcoins now.

I agree with you, because if someone ask like this question so its mean he has a big amount and he want some advice and than he read answers and he choice the way which he like more than others. Also it is guide for us, in this way we see which is the best way where people want to invest it.
