But bitcoin ain't a bank.
It is a currency.
The survey made the wrong comparison.
It should be BTC against USD or its own currency and digital currencies.
Bitcoin doesn't give an annual interest like banks. Yes, the price of it is moving now and you could make profits out of it but that means selling your bitcoin with a different currency.
This is correct, but Bitcoin is also enabling people to bypass banks. People were led to believe that banks are a necessary evil, but they are not. Of course, with fiat money, any amount you keep by yourself is losing value, they do this on purpose. In their biased view, the "punishment" is meant to make you invest or spend it by force, and with this they justify their dogma that no money cannot keep its value, our of feat that, the horror, people would save it instead; thus stagnate their model. Which explain their insane fear of deflation.
Enter the Austrian school of economy, which a century ago was telling people they should use gold, not fiat. They warned the dangers while in the roaring 20ies, pretty much predicted the crash of 29... If the money doesn't lose value, people don't need to spend it all. In fact, people only need to spend what actually needs to be spent. This leads to saving it, but not in a bank; but by yourself.
The modern bank, with its legalized Ponzi scheme known as fractional reserve, seems to "magically" keep some of the value of fiat, by offering interest for those fool enough to trust their money to them. In turn, its not like they just lent your money to others, they also introduce at least 9 times the amount of that money (out of thin air) into the system, which is even worse than printing (but close).
To break the scam the banks need to change, but they won't, so the next best is, to not use them. But your fiat is losing value, so either you change it into some asset, or, a money that doesn't lose value over time, like bitcoin. Note that the Austrians meant actual gold, not "gold backed" currency, that's garbage. All pegged coins (so called "stable" coins nowdays) live on a promise easy to break by the small group that controls it when things turn bad. The USD for example where Trump prints as much as he wants like it doesn't matter, and scam coin Tether doing 30% fractional reserve according to their promise (good luck auditing that, and they have already broken that promise at least once).
And then there is the whole privacy invasion issue, and the requisites. Many of you are probably biased, think opening a bank account couldn't be easier, but that's not the case in all countries. There are places where you are forced to provide so many things you might have an easier time getting your elected official to actually deliver on their election promise than a bank letting you give them your hard earned money. You need proof of address, proof of nationality, a good amount of money and often, having accounts in other banks already (which makes opening your first starting account kind of tricky).
You know it is fine to get rid of them, and I'm no millennial, but i hate banks. Cheques were still in wide use until recently, a few years ago before hyperinflation finally moved in. Those things, took
days to cash, and were highly prone for scam, you had to ask the bank on telephone to find out if the person had the money wrote in the paper before taking it as a form of payment, and then you had to rush to the bank to cash it out (usually in a way too long line) so that the money was still there...
Yet some people have the nerve to complain of a 1 day confirmation on super secure Bitcoin
instant transaction...
The only problem with actual gold, is that being physical, you have to protect it and yourself of thievery, and of course it gets heavy. But Bitcoin is better.
