The issue of Trust is not only evident in relationships, it is applicable in our daily endeavours. People are more committed to system they trust than the one they don't trust. Even in this forum, you can easily do business with someone with a positive trust than one with a negative trust.
As the saying goes "wherever ones treasure is, there his soul is". So, in this article we would try to establish if ;
1. If people have fallen out of Trust with the Traditional banking system.
2. If people can trust BTC than banks.
Discussing issues 1. I'll use myself as a case study;
Most times I would feel cheated by my banks even when I have no evidence to prove same. I always have this feeling that a bank with over 3million customers can decide to deduce 0.5cents from each customers account without sending them alert. The customers may also not notice because the figure is small. Multiplying 0.5cents by 3m customers will give you $1.5m. I don't know why I always believe there are hidden charges in the traditional banking system.
Secondly, data management: I know of few companies that pay hugely in order to know how people spend their money, on which products, which days and which class of people spends much.
This company can quietly walk to the bank and get these information. They will pay the bank, and our data would be released to them without our consent. Because, with debit cards, how often you visit the grocery can be determined, etc.. I also feel cheated here.
Further; information privacy is another concern of mine. In most cases, the bank can give out your bank statements or any other salient information of yours to the government or public without your consent.
Considering my above worries, the issue of trust in the context is therefore not limited to trusting your bank to save your money, but also trusting them with your personal data.
On this premise I created a poll to know if we still trust the traditional banking system or we would rather trust the BTC (self bank).
You are right and all this points cannot be totally ruled out of what can happen to your accounts balance/information at the Bank. The first scenario you mentioned actually happened in a my Bank but not directly by the Bank but from a staff of the Bank how have been withdrawing small amounts like that from customers accounts for a long time before it was discovered and the staff was arrested and confessed to it but what happens if it was the bank's themselves involved?
Even when we don't have that full trust for Bank's, most times we do not have the option but to continue to deal with banks until we have more and more places to spend Bitcoin and other cryptocurrencies directly.
