of course many people would think of doing trade as key to getting big advantage is the large capital:D
with a capital of 10 BTC it could take to become rich. because bitcoin doubled in trading can be done within a few days.
what is needed is patience to trade

I will use it to charge my wedding. I desperately want to get married but the money I have at the moment is still not enough. if it is true, I will build a happy family.

Just trading!..

More secure than gambling or other things... You can double or triple your investment in a day!..

If it is the case I will also put it in a wallet paper and secure it. I believe the price will fluctuate in the coming years. Who knows maybe a bitcoin equivalent to a million now. Also to note that there is no inflation rate like USD and other government controlled currencies.

Ill would invest it back into bitcoin,

if someday you will give me 10btc the 1btc i will gambling it trying to triple it or more than that and the rest i will cash out and buy some goods

If I have 10 BTC, first I will keep about half in cold wallets.

I will set up a faucet to share some bits with people and donate 1-2 to Charity. The remaining will just stay in my hot wallet for spending whenever possible- but of course I will buy back to make sure the amount is not running low....

I guess 10 BTC is still not sufficient to allow my retirement yet...

most probably i wouldnt do anything with those money because i would like to invest it more in order to make even bigger money in the future by just waiting for a huge increase that will happen

i think that bitcoin block reward halving might be the key because during it people will buy a lot of bitcoins thus making the price go up significantly i hope my predictions will be correct

We respect what everyone decides to do but do note that trading isn't for everyone, still even if given 10 btc. Trading just requires a lot of skill. I've seen quite a few "traders" who, even with proper knowledge, lost a lot (~5-50btc) because of bad prediction.
