I am more curious to know how they share some similarities. Like really how haha. if you are holding BTC BTCin your personal wallet how you will lose money? Besides you should say for the temporary time frame or for a particular time span the value of your holding might fluctuate but it doesn't means that you will lose anything.
I you really think its a loss than I cant say anything, if anybody else feels like this I would recommend being patient and wait for the moment of truth you will not regret exiting the market in loss.
The fact is that not everyone can withstand this period, when the balance on their wallet is significantly reduced due to the price drop. Those who sell during this period will lose money, but this is a rather long process and it will not happen as quickly as in gambling.
In any case, it is not worth comparing bitcoin trading with gambling, especially long-term trading, because these are different things. With proper understanding, buying bitcoin for the long term is almost a win-win option, and gambling contains much more risks and gambling is much more dynamic than long-term trading. You can always find a less risky option if we are talking about bitcoin, but it’s hard for me to say this about gambling.
