What you should try is to find the right balance between how to keep the business stable and profitable, and at the same time to invest at least part of the money in Bitcoin or something else that has the potential to bring you long-term profit. Of course, this is not easy considering that obviously your entire business depends on Bitcoins, which means that you always have to take into account volatility, which can often be much more pronounced than inflation, which affects purchasing power due to inflation.
Is there perhaps a way to try to start another business that would be connected exclusively to fiat and thus have two parallel sources of income, so that you can keep most of the BTC for the long term?
