Pretty good post. Crypto does appeal to people who don't have a lot of money to invest. It is the beginning of a brand new type of currency and we are just getting in on it. Most people don't even understand how it works yet or think that it's a scam. Although, honestly, a lot of people think that about foreign exchange and the stock market too. The delayed gratification necessary to lay out your money for crypto instead of toys and gadgets will pay off.
Cryptocurrencies appeal to everyone not only to those that do not have money, now more and more institutional investors are putting their money in bitcoin and this is not really surprising they can get more profits in bitcoin in a single year than what they will get in many years or even decades in the traditional markets so bitcoin as you can see not only appeals to those that do not have a lot of money but to those who are rich as well.
Institutional investors prefer investing in ETFs rather than directly dealing with the crypto-currency (mostly due to issues such as taxation and legality). But the problem is that the SEC has blocked all the proposals for a Bitcoin ETF.
