You can't make money by betting on something with a valuation of 800bn which is the cryptospace.
The cryptospace as a whole you cannot make money from anymore, the only thing you can make money from is betting that the marketcap of old coins such as BTC will flow into new coins such as ETH.
But that if you are gonna do that, then it's better to just do it on the stock market, by betting on new companies replacing old companies and taking their marketcap
