First of all most people do not even have savings to begin with so they have nothing to store in bitcoin, if things were different then we could see bitcoin serving as a store of value for them, the same happens with gold by the way, do you think that people actually are holding gold? Except for those that have a few pieces of jewelry made of gold the rest of the population is not holding any so that is not something that worries me at all.
The real challenge come from everyday use, the fees are very expensive and as long as that is the case then making small transactions is not an option, you can do several things to lower that cost but even those measures are not enough so we will have to see if the lightning network which was the proposed solution to this problem actually works as advertised, if it does then bitcoin will also become the coin that we will use in our everyday transactions.
New Survey Reveals 12% of The American Population Owns Gold, While 14.7% Owns Silver
https://www.prnewswire.com/news-releases/new-survey-reveals-12-of-the-american-population-owns-gold-while-14-7-owns-silver-300942963.htmlOne recent survey showed that 11% of Americans own Bitcoin, which would mean about 30 million Bitcoin owners in America. Another study found that about 5% of Europeans own bitcoins (37 million owners).
I really think there is a great overlap there, most of the people that hold gold also hold silver and most likely they also hold bitcoin, at the beginning gold holders were against bitcoin but now it seems they are slowly understanding that bitcoin is also an option for them to hold for the long term as it has several qualities that make it better than gold.
Still what worries me is that when the next crisis comes many people are going to be left with nothing as they have no assets that can be considered to be a store of value, real estate most of the time follows inflation but when there is hyperinflation the price of real estate goes down dramatically as people scale down on their living expenses and one of the first to go is the big house.
