Bitcoin is the only one in that list that actually has a real value on it and that is if I really had to choose one out of that list. If more people saw what Bitcoin can do then the price of Bitcoin could go up so high that there wouldnt be that many people wanting to sell it. Bitcoin can give people somewhat of a free income if they decided to hold the coin.
