Many large corporations, including Honda, Dell, Samsung, and various microbusiness merchants, have already integrated Bitcoin in their operations.
You can get it right now if you have the ability to buy Bitcoin in the amount you can afford. Either you wish to earn money here, or you can save for the future. However, it is mainly wealthy individuals that invest here for long-term gain.
The only reason why its like its always hard for some people to hold their bitcoin for the long term is due to lack of reliable or dependable source of income, if a person can have a good of income they can depend on, i do not see why it should be difficult for such a person to buy and hold bitcoin for long term, regardless of financial status, rich or poor, or middle class.
