holding bitcoin for long term is only possible if you are having enough income for your holding period.
Because I do see many people are spending their bitcoin savings when they face any need of extra money. This is due to they are not having strong resolution for saving bitcoin for long periods. They are deviating from the plan of becoming rich as they are spending bitcoin time to time.
Yes, earning bitcoin is harder and saving is much harder but the real challenging thing must be holding it for long periods without spending anything. Because, if you start spend in small amount from our bitcoin saving, we might end up with no bitcoin saving after certain point of time. Then the dream of getting rich with bitcoin may go dream for ever.
