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.
Its not a trophy that when you earned it all you have to do is display in a good trophy case and that's it. You have to use it so that circulation of Bitcoin will continue but of course make sure that what you will spend is already the profits/fruits of your labor from you capital. You have to enjoy and your profits or else whats the purpose of investing in it.
