You’re right, many of the biggest winners are ironically probably the same players. Probably lots of white, well educated, male, geeks. But the barrier to entry is way lower. Consider rules against “pattern day trading”. Sometimes to make more than 2 equity trades in a day, you need $25,000. To invest in anything besides bare equities, bonds, options, you need $1M+. This is US specific, but it’s common. Average people are literally not allowed to trade “exotic derivatives”. Cryptocurrency opens up the option of putting $100, $500 or $1000 (some tokens sell for fractions of fractions of a penny) into a range of games, derivatives, and other assets that you can trade 24/7, 365. You can create one yourself and make it available to everyone in less than 30 minutes, for free. You need a web browser and some money or credit (not much). Pay your taxes, and you’re good to go. The other options available to people are boring and take decades to pay off on average even if you do it right. But they provide the same thing - no one really cares what stock they own. They are speculating, playing money games. I think there is huge pent up demand for money games because it’s so hard to get into “traditional” finance. Even if you get in, there’s very few games available to you on Wall Street.
And you’re right it is the same economy, just open to all, and with way more fun ideas like flash loans (impossible in traditional finance), no-loss lotteries, decentralized automated market maker exchanges, tokens you can stake for other tokens that represent the interest and the principle which can then be traded again, etc.
Should it be allowed? Up for debate. I’m strongly against any rule that says “you’re too stupid, this is for your own good”.
