Yes, Capital can compete with Strategy for sure given the enough interest into buying Bitcoin, risk taking and enough funds.  The accumulation race may push Bitcoin to a new All Time High but it would not be THE factor to do it.  Bitcoin has still not priced in the new block reward post Halving.

Now about how long I would be holding for, I am not holding until Saylor or Capital is.  I am holding Bitcoin for what it provides.  Third parties are not an interest to me.  Even if Bitcoin 'dies', I would seek an alternative.  It offers me a feeling of freedom and safety that I will not give up for a matter of profit.  Particularly considering the history of Bitcoin shows it will likely only provide me MORE profit years down the line.
