This isn't just gambling, traders chasing early meme tokens are also gambling, as they're trying to buy new tokens that don't yet have high liquidity. The difference is, they don't call it gambling...
Even if a trader trades meme coins, and at the same time adheres to risk management, using a small percentage of the deposit and at the same time using a stop loss, then such trading will not be a casino, since these are completely verified actions on the part of the trader.
