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.
It's not going to be as quick as gambling but if they buy and hold bitcoin for long period of time then they are going to make a lot of profit for sure. I can be sure that I have been making money since I have been holding bitcoin and that has been a proper period for sure. I am not saying that it's granted but that doesn't mean that it's not a good result neither. Sure it's not going to be guaranteed but you could make some profit with it without a doubt.
I think people who are trading with owed money for example are gambling, or people who do not know much about leverage and still do it are gambling, but when people are holding long term means that they are not really gambling and they know what they are doing as well.
