I have a feeling you either do not understand what I am saying or intentionally do not want to hear rational arguments. No one is saying that crypro is bad for speculation - people can do it any time they want to. But it is speculation, not investment. The difference is that, in order for someone to win, someone needs to lose. With stock investment the "average" person wins because firms make profit and stock pays dividends. You can make a parallel between options/futures and crypto - all of them are zero-sum game and all of them are, in some sense, just a lottery. The major role of forwards is to hedge, so, if you sell corn forwards and you are not a farmer who expect to produce corn but some schmuck who simply thinks corn will increase in price - you are not using forwards the way they were intended, you are using them as a casino instead and I would say the same thing to him (i.e, he is an idiot) as I say to anyone who wants to trade crypto. Learn the concept of optimal investment portfolio, security market line, and capital asset-pricing model, and efficient market hypothesis before doing any trading/investment on your own.
