I think 10 bitcoin is a good amount to be hold for next high rate. the market is now a little hanged the reason is some uncertainty in the world of crypto currencies but the problem will be solved very soon, the bitcoin market has still a lot of potential I think still it is the best time to invest and hold bitcoin, because I can see that in next few days the rate will grow up so quickly.

I think he should not have to sell all of his coins, as the price will increase the whole year and the better decision will be that, he only sell the profit from there, so he will get a continuous profit.

Yeah if you are able to make profits at current price then nothing wrong in selling some of your coins and hold the rest for halving, as we may sell all time high at halving.

I'd store the BTC somewhere safe (keep it in an usb of some sort) Though i'd really keep in mind that BTC can change anytime, thus keeping it stored wouldn't be such a good decision.

or maybe invest it all in stocks and trade it up to even a higher amount... who knows... I'd really want to try out the stock trading and see how it goes from there.

It still depends on when you bought the coins. Even you see that the price is soaring high if you just bought recently then it still not good to sell your coins.

well i would buy some things which i want to buy and put some for trading and invest some in something and i have plan to start a business where i can buy/ sell products through bitcoins and keep some safe in my wallet for the increment in the price of the bitcoin in future:)

I will exchange into fiat and start a new business,maybe an internet cafe where i can teach my family and customers about bitcoin.

it was nice, if I was given 10 BTC, I would probably sell 8 BTC I have to open a new business in the real world, and 2 BTC would I use to make business on the internet

nothing do if i get 10 BTC.just reserve it and when btc will up, i will sell it with high price.. and sure than it will be up for little
