The question is what are the possible means of securing our businesses and at same time saving the bitcoin made through the services we render?
For me, it's simple: working towards holding Bitcoin means you need to have another income source that you are earning from, and then you will have no need to spend your Bitcoin if not just to hold it. Second option is, while spending your Bitcoin, never spend everything, always learn to save some and hold tight unto it.
Like the guy on the OP who said he sold his product for 14 BTC, meanwhile he could not just save up 1 or 0.5 Bitcoin out of the 14 he received as payment.
There have been threads where OPs were asking what people would do if their salaries were paid in Bitcoin. The answer to that question is also simple. Perhaps, let's assume that Bitcoin has been accepted globally and salaries are paid in Bitcoin, the truth is that not everyone is going to save up their salary. We will still have the poor and the rich, those who will earn such a great salary in Bitcoin that they can satisfy all their bills and still have some Bitcoin to allocate to their safe (holding or portfolio). There are also the middle class and the poor who can receive a small salary in Bitcoin, and they will spend it all on all their needs.
Based on the above points I have made, and to answer your question, for one to be able to hold his or her bitcoin, they need to have a budget for their spending and also have self-discipline to save. Because if you earn in Bitcoin or sell some products in exchange for Bitcoin, you definitely have needs to spend those Bitcoin on, but the ability for you to only spend some of the Bitcoin and save some for the future is what helps you hold the Bitcoin.
I don't know if you get my point.
For example, if you have a business and you accept payment only in Bitcoin, perhaps that business is your only source of income, which means you will feed from the profits you make on your business and you will still pay some bills from the profit you make in your business. For you to pay those bills and settle your needs, you have to sell some bitcoin. You cannot hold all the bitcoin you earn forever if your business is your only source of income and you depend on it for survival.
Let me give another example. Imagine I am working for a company and my salary is $400 per month, which is normally paid in Bitcoin. From my salary, I have bills to pay and financial responsibility to handle, which can take up to about $390 worth of bitcoin. That means in that month, I am only able to save $10 worth of bitcoin of my salary for that month.
The question is, what if my salary of $400 worth of Bitcoin is not even going to cover 50% of my needs for that months? That means I am going to spend all my salary and won't hold anything.
So, the solution is that, while earning in Bitcoin, you need to cultivate the habit of saving some portion of your earnings and don't spend it all.
If you are running a business and receiving payments in Bitcoin, and perhaps you are scared that the price of Bitcoin is too volatile, you can equally covert your Bitcoin to Fiat, but before you do so, make sure to keep some Bitcoin fraction that you wish to save in your portfolio. If you keep gathering in the ban, before you know it, you will have a full ban.
