In order to benefit, will I have to cash out bitcoin when it gets high? That would mean i would have to sell it for dollar or other currency.
When i am buying online with coin, if it says the shirt is for $25, will they calculate how much $25 is worth in BTC at the current market rate or
how much it originally started with? If its at the current market rate, then whats the point of bitcoin if i am not profitting?
The purpose of Bitcoin itself was to be used for peer to peer transactions. So the price has to be the current market price for every thing you want to buy. You can make profit while purchasing things since then it will act as a mode of payment. If you want to take the profits out then you must be trading BTC. There are differences in these things which you should understand.
