All large enterprises keep cash reserves. Whether you agree or not, the prevailing thesis behind keeping cash reserves in BTC is not that it will turn a profit, but that it will avoid devaluation like USD.
Historical data hints that we are not close to the peak of the current bubble and when BTC drops it probably won't be lower than today, or at least, not for a long time.
Of course there is also probability that the 12-year trend will crash into zero, but that probability dwindles with every year Bitcoin isn't broken and every popped bubble that lands on an even higher low.
