I think the entire market also knows the dollar is going to get strong this year. Two rate hikes at least are expected and we could even get one as early as March. Effect on risky assets like Bitcoin is supposed to be evident but I'm hoping that all this selling is already due to people expecting that, so when the hike does come, we should be safe.
You are right, in fact this is a speculation that many are doing and that is not unreasonable, however when evaluating the behavior of the dollar and the BTC, for many the BTC does not fit for now, but at any moment the BTC can give a very high bullish turn, when this happens, any token that comes from good projects or that has to do with casinos is likely to go up, because the trend will now be towards the safe, and BTC and casino tokens are considered safer, this due to the experiences of many investors in NFTs.
I know if you go into Bitcoin speculation or discussion on this forum there are a few people who disagree that dollar will have an effect but at the end of the day every investor to me thinks about dollar and others. "Others" to most investors simply means anything they can put their fiat in like stocks or cryptocurrency, which is to me why stocks and crypto seem to follow each other in market ups/downs.
I'm not sure what NFTs has to do with this though. I see NFTs as a hype, that followed the Defi hype, that followed the ICO hype.
