Holding bitcoin is not the same thing as trading bitcoin. Gambling and trading are not the same thing too. Trading require you to learn trading skills but gambling require just some strategies. Trading can be risky like gambling, but they are not the same thing. If the price of bitcoin fall already, you can invest for months or years and you will most likely gain.
Trading is risky like gambling but not as risky as gambling. When a trader makes a wrong entry in trading then his balance is not 0 and he has a chance to recover the loss by holding those coins. But in case of gambling, if one makes a wrong decision, his balance immediately becomes 0 and if he wins the bet, he gets the profit according to the odds. So these two things are not the same there is a big difference between them. However, leverage trading can be said to be a form of gambling, but spot trading is never like gambling
