I prefer saving bitcoin just like you and the main purpose behind my saving is for the future. I am positive about bitcoin and I am sure bitcoin price will be sky high within the next 5 years. It may go up to a certain level which we are not able to think today. So with this hope, I am saving bitcoin and not investing it anywhere apart from trading.
I have a dream of buying something luxurious for myself and family in future and I am sure that my bitcoin savings will definitely help me to reach that dream and make it a reality. I will continue earning bitcoin for another 5 years and then I will sell that to for fiat currency to fulfill my dream for good.Consider bitcoin price which could significant increases in few years, then it suitable as savings for future purposes.
Yeah, who decided to hold bitcoin should have faith in it as the market fluctuations could affect your decision, the best way is saving without looking at the price, and never sell it to get profits but wait until certain time.
