In its core, every investment is already a gamble. Whether it be stock, cryptocurrency, or establishing a business. So comparing the current market to a casino isn't really wrong. They just vary in degree of risk, and considering the crowded altcoin market where altcoins are having a hard time increasing in price steadily, rather only driven by FOMO and hype, it's just a gamble on where investors would invest their funds. That's why not until some altcoin has been made to revolutionize, Bitcoin would still remain on top of the market.
