Perhaps, split the retirement account into bitcoin and a stablecoin?
Yes, as long as our expenses are in fiat, we need either fiat or stablecoins at least for current expenses and to cover the downturns in the market, which means a few years' worth of stablecoins (maybe 2), if planning for retirement. But that's if bitcoin keeps going up. And for the long term, we can't assume that will keep happening. So, either changes will be made when that doesn't happen anymore, or a more balanced approach is better.
Yes, I think that will work but it may also require an almost constant monitoring of the markets and adjust when changes happen. Weighing the potential upsides over the potential downsides for the long run can decide whether if it's worth it or not. Some might not be comfortable with that volatility, especially when it comes to retirement money.
I agree. Seems risky to do that with retirement money, as long as the majority of expenses are in fiat.
