You are right that the governments are tightning crypto regulation in general but no much pressure on crypto derivatives, I do not think there is much to be worried about, if a certain country governmental laws do not favour, there will be some other countries that will favour. About crypto derivatives like margin and future contracts, I do not think this can be affected, there will be many exchanges that will always be providing these services. Although, the KYC, AML and CTF of users using the exchanges can become mandatory in accordance to governmental policies, but this should not affect crypto derivatives.
But nevertheless, new options for trading crypto derivatives have not yet appeared, but the old exchanges have already regulated. So far, the wave of regulation is moving faster than the wave of new trading options. Perhaps they will appear in the future, but so far they are not. And you have to either abandon these exchanges altogether, or accept their terms.
I would not have paid attention to it so closely if it had not started happening so abruptly. In fact, over the past 3 months, a bunch of bans have sharply emerged in this area, which was not observed, say, in the first half of this year.
