In crypto we trust?

On each bank note of USD there is a famouse motto “IN GOD WE TRUST”. These words have a real sence in the country, where the quantity of churches is almost equal to the quantity of schools and parking spaces in front of them are almost the same size as those of shopping malls. So I have a question: are there any financial and economical signs that may let us agree with a similar motto “IN CRYPTO WE THUST”?
We have no signs from the society that it needs all those decentralization facilities, declared speed of transactions and many other features of crypto that its followers proclaim to be the mane advantage over usual financial instruments. For example there were quite a few ICO of projects that declared its goal as inclusion of unbanked people to the financial system of the world. But if we try to analyse this goal we will have to ask ourselves: why are there unbanked people in the wolrd of mobile internet and total globalisation? May be it’s not because the existing means of communication do not let these people have permanent access to any kind of a bank service, but because they simply have no money and no bank account? Surely this is the reason: those, who have no money, they have no need to be banked. So what crypto projects can do in order to include these people to the financial system of the world? Send them free crypto coins as some ICO do airdrops and bounty programs? Are you kidding?
Crypto has its own history. Even though it is not long. But even inside this short period of time there was a huge growth and a drammatic failure. When there was a growth all “crypto experts” would sing songs about the brilliant future of crypto and announced price of Bitcoin up to 1 000 000 USD. There was a trivial hype that made lots of people first get interested with the news about crypto and then it made people invest in it. The growth of crypto market capitalisation was not bullish at that time. It was tyrannosaurish. That is why lots of ICO made thousands percent income to its investors. But without a real product in any market the invasion of a capital will make a ballon that will burst one day. When it happened those “crypto experts” would tell stories about “whales” that want to dump the price in order to buy crypto at a maximum low. Also they would complain that the authorities of the USA and other countries create different obstacles for developing world of crypto. But what do we have in the long run? Can you name any kinds of real products made with crypto? There’s none. May be this is the main problem of crypto? Or you will call all those beta versions, conferences, meetups, announced partnerships and crypto wallets as something that can be treated as a product? Are you kidding again?
If you think that I am too pessimistic I will agree with you. But give me any reason for optimism, please. For the time being I can say that with the slogan “TO THE MOON!” investment in the space program of Elon Musk is more safe and reasonable than investment in crypto.
