(I am not planning to implement such a contract myself, although I have investigated a bit how it could be done. But if someone would implement that thing, I'd be really interested!)
I will put aside the existing speculation for now, I will focus on my personal speculation.
In short, I personally will implement Bitcoin investment decisions for the long term, for now I am not emotional.
There are several reasons I want to invest in long-term contracts in Bitcoin, [1] supply is inherently limited [2] Extreme Volatility.
These two factors are enough to make me confident in the long term, I still believe that with high demand for Bitcoin, theoretically in the future it could push the price of Bitcoin to increase.
I still believe Bitcoin investment is not the same as traditional assets, meaning that even though the current market price has touched the $58k level, My speculation will definitely experience high price fluctuations due to volatility, of course this is like what happened previously once every 4 years, 2028 to be precise.
