One such use case I just mentioned, i.e. receiving B2X tokens in a safe way
I might be proved completely wrong but I'm personally not concerned about the fork having an adverse effect on BTC price. I understand there are risks but my assessment is that it one that I'm willing to take so I'm just leaving my BTC lent out. The BTC I have lent out is for the hodl, I'm not selling anytime soon. The interest rates are already starting to increase as I think many are taking them out of lending so I'm just benefiting from that.
There might be a dramatic squeeze when Bitcoin futures are allowed since it doesn't take a lot to bring Bitcoin down Soros style (even if temporarily)
The CME announcement last week could have a huge impact, in fact, I'm convinced it has far more to do with breaking $7k than the fork does. I'm hoping they get the necessary regulatory approval because I'm itching to day trade BTC futures on a real trading platform. It will be scalplicious.
