Do not hold for so many years I suppose but it may be 2 3 years enough. After you just sell the bitcoins and you will be amazed to see the earnings you will from it.
True. Even I had try this. Holding and saving is the key for success in bitcoin. Sell you bitcoin only you want money. Just check the bitcoin rate day to day while holding. Once the price of bitcoin reaches the moon means, you will get very good profit from it. It may be a dollar, Euros and so on.
If everyone holds, who will you be selling to in the future? Who will be buying your bitcoin?
I agree it's profitable now and it has been longterm until now, but I don't know what mechanism would keep it that way in 5 or 10 years. Purely trading day to day is enough to pump the price short term. New holders pump the price long term. As more people become holders, there will be less bitcoin to trade and the market will become very thin and bitcoin very expensive. Won't there be a time when a new buyer will avoid buying 1 bitcoin because he doesn't want to go in when others spent the same amount of fiat for 1000 bitcoin?
