I am just intrested - is any bitcoin holders are intrested in investing in ICO which pays out in bitcoins? or fiat is much more intresting?
Anywhere you want because bitcoin is like a regular paper currency and you can use it anywhere in the country. But my suggestion to you is that you must wait for some time and when the price grows more than you can use your bitcoin for your future dreams.
The most favorable use for me is in the future when we dont have any job and cant do any more work. Then we will need money of our own to spend the rest of life comfortably.
I think of bitcoin as a great investment itself. If you are having bitcoin in your wallet, then there is no point of investing your bitcoins in some other kind of business. In fact, you should go for holding of your bitcoins and that for as long period of time as you can.
It will help you in earning a very good amount of money at the end. All you need is to sit back and relax no matter what the conditions are.
