Some people think that Bitcoin is so good that keeping there business finances or income in Bitcoin is the best idea forgetting that it is very wrong to do that.
As we all know bitcoin is highly volatile in nature and so when you keep your business income or money in Bitcoin it risk you losing some part of your money and also affecting your business because Bitcoin can drop in price at any minute and when that happens the money you kept in Bitcoin will drop in price and since the money is meant for your business the drop of it will affect your business financially and can lead to the fall of your business, money is what they use to run a business when there's no money the business will fall.
So don't keep your business money or income in Bitcoin so has to avoid lost, keep your business money in Fiat currency or a stable coin like USDT.
Yes, normally a business is run in such a way that first a capital is invested in a product and that product is sold and the product is bought again with that money, thus the money is rolled over. So since Bitcoin is a volatile currency, if the money for selling that product has to be kept in Bitcoin, then if the price of Bitcoin goes down, the profit margin may decrease. And then it will become very difficult to grow the business. Doing business is a kind of risk, and accepting Bitcoin as payment will put it at even greater risk. So in the case of business, it is always better to keep fiat currency or stable coin as a payment method. And it is better to consider Bitcoin as a separate investment asset.
