if i got 10 btc i will add them to my fund in trade to get more profit, for now i'm trading with only 1 btc and make a nice profit but if i got more it will be a great think, or maybe i will just save 3 btc and use the rest.

Halving is a big expectation of the every user. Right now holding will give the best profit than the other earning method these days.

Well i would invest a part into some project related to bitcoin ,im collecting bitcoins to make my projects live,soo i believe you can make your own project or invest into lending or try some altcoins but the best reward always come from own projects like the person who runs exchanges as well casinos where the most of bitcoins are being used.

Majority of my coins will use for trading, and rest will hold for the future so  If I suffer loss in trading then I can recover it by selling rest when price goes higher.

there are many people who use 10 BTC to create a business, 10 BTC worhth $ 4,000 was enough to be used as capital,
but it seems not enough for the $ 4,000 cost of the holiday?

I will save it surely

I would use the money to invest. I will make trades and then earn a profit. My target is 10 BTC can make money you give. to 15 BTC after I did my job.

If you hear the word investment, of course it is a risk. so I better to grow in its own way, than to invest.

Pound your grand-ma with my man meat untill she begged you to pay another 10BTC to make me stop.
