Bitcoin will have a good future. I know that as much as 100 percent sure. But it is the risk that you should take to invest now.
But I think we all hope later for a good future for Bitcoin. But you never know what can happen later in the future and that is the problem.
Don't you think your statements are contradicting each other ? If there is a risk in the investment then you are not 100% sure about it.
Though,I don't think that any investor can know the future anywhere around the world, so it is not a problem of bitcoin or anything else if you don't know the future..lol
