Most modern businesses are adopting Bitcoin because of its speed and borderless ability to without the involvement of a third party, and also those businesses stand the chance to gain from the profits if Bitcoin price rise within that period their holding it.

I Think it will be easy to use for everyone. Bitcoin is digital crypto. Already many companies accepted bitcoin and they invested also I Think it will be accepted all bossiness companies.I think people will their money convert to crypto in future.I Think it will be fine and beautiful and more interesting.

Well you did said about volatile so that's one of the reason why some of the big companies or even the smaller ones are not gonna accepting bitcoin as their payment because of how volatile the market is and it could either make the company profit of their bitcoins or things will go in the opposite way. The other reason is transaction fee but it's not a big deal.

Steam was accepting Bitcoin for quite some time but unfortunately they removed it: https://hexus.net/business/news/internet/112973-valve-removes-bitcoin-payment-option-steam/

We are entering an era where almost all payments are made cashless, therefore some businesses are starting to accept Bitcoin payments. And that's
what we really want as Bitcoin supporters, because the more businesses that accept Bitcoin, the faster the adoption process. But the fact is that Bitcoin
still has some shortcomings, therefore the number of businesses that accept Bitcoin is not much. Some of the considerations for business owners are
the legality issue and the volatile Bitcoin price. We know most countries in the world have not accepted Bitcoin as a means of payment, therefore
business owners do not dare to accept Bitcoin payments. In addition to the volatile Bitcoin price, it can cause the profit generated to decrease,
so the risk is indeed big. So it still takes a long time until Bitcoin is actually accepted as payment, so we as Bitcoin supporters must be patient.
But I believe in the future, most businesses will accept Bitcoin. For now we should be grateful that at least we can use Bitcoin as a digital asset first.

I think theres a few benefit if business accept bitcoin payment.
1. New marketing opportunity. Telling people that you accept crypto might boost your sales in no time.
2. Lower fees. Credit card payment providers charge merchants 3% fee and more for each payment. Crypto payment providers charge significantly less and can convert those received coins to fiat and send to the bank account, so it’s a good opportunity to save some money for the business.

The skyrocketing number of bitcoin users took all businesses by surprise, even during the pandemic that made many businesses drop, the performance of cryptocurrencies was unstoppable, this made business owners immediately think about accepting bitcoins for payment.

They may looking for adoption but does not count until it happens, there are many countries considering this fact but yet what are their stand now? still on process for years?
let us not count the chick when the eggs are still solid.
bitcoin is really an outrageous innovation for the whole world but appreciation is not enough instead we wanna see understanding and adoption because that will make this market grow much high than what we have had now.

But what about the issue of volatility of bitcoin? Say for example that a person who works from a big company starts to accept bitcoin as a form of his/her salary, yes we could safely say that bitcoin now is on the hype and currently $61k. But what if the value starts to drop dramatically, maybe the remaining option their is to hold that crypto and wait for the market to recover.
Yes truly, we must dance according to the music and keep up with the time. But I still think best that the employee can have an option of to receive the salary by cash (fiat) or in crypto form.

not just that instead how they can earn high as the value of bitcoin now are more cheaper compared to the incoming prices when the adoption finally comes.

if they are aiming to collect bitcoin(as holders) then this is the best way to accumulate more and more bitcoin to be ready in the years to come.

it is more on today as the ETF seemingly bringing hype in the market

i think this will also help more people to understand what this crypto can bring to them .

I agree with what you said that the company can gain in 2 ways. Thru profits coming from the sales itself and at the same time, capital appreciation coming from Bitcoin.
On the other hand though, the company can loss in 2 ways too instead of one. Thru losses coming from the business itself and with capital depreciation coming from Bitcoin.

Lets also take note that this adds risk to the owner of the business since Bitcoin is very volatile, there might be a chance that it will go down at the time when they need to sell it and vice versa. I would love to see businesses accepting Bitcoin though since it adds to the adoption rate and its another way to market it. Maybe in few years, we may see more and more businesses accepting it.
