My thought is,bitcoin is not like gambling.You can refer other digital asset in the crypto space to as gambling but not bitcoin.The reason why shitcoins are likened to gambling is because their outcome aren't certain unlike bitcoin that keeps introducing new ATH.Op are you referring all cryptos to as gambling because they aren't used for payment or what, because I still don't get that part that bitcoin is used because of it's store of value.The adoption of Bitcoin doesn't rely solely on its value for long-term investment, but also on its use as a means of active trading among merchants globally.
The truth is everyone can choose to believe or agree on Whatever they like that seems okay or convincing to them, people approach Bitcoin differently and what I mean by this is that some people gamble or trade Bitcoin because they feel they can and they feel that is the best for them while some people invest in Bitcoin and hold for years because they also feel and think that is the best way for them so either ways they are both correct with their definitions but what matters is the result they are getting at the end of everything, so yes Bitcoin can be seen as gambling because it is trade able.
