I have only gained good things from cryptocurrencies (they have changed my life for the better), however, I am frustrated at those who are in for money, and only money. They hurt themselves as well as cryptocurrencies future. I am sad that I still can't use bitcoin to purchase the things I want, as it isn't used as a payment currency/method. I am sad that there are big financial institutions that want (and do their best) to wipe the crypto world out, and instead of working together as a crypto-community to thrive, we are fighting, arguing, and scamming each other. Where I live, the government relentlessly tightens and destroys our financial livesI was lucky to have found salvation in cryptocurrencies when others struggled.
We need to show the world that we are not just a bunch of wanna-be millionaires, that we actually care.
You can't blame someone if he admits that money is the primary reason why he is into crypto-currency. I don't think that there is anything to be ashamed of it. My opinion is that we should be proud of the fact that crypto-currency is helping hundreds of thousands of people to earn a passive income.
That said, there are a lot of people who are in to cryptocurrency for ideological reasons. And there are far more, who are into this sector due to a mix of both ideological and monetary reasons.
