Some people will indeed laugh at this kind of decision because they don't know how Bitcoin moves and assume Bitcoin will continue to fall.
Odell Beckham's decision was the right one, and he is now certainly making a huge profit because of the decision to receive a salary in Bitcoin.
A simple example of this Forum is the Signature work we do.
we actually receive Bitcoin directly every week for our salary as long as we are signature participants, That's a real example of work paid with Bitcoin.
Imagine if you keep Bitcoin payroll from the beginning of Signature maybe 2019 until now, it will generate tremendous profits.
But more are selling back to Fiat for survival needs, but it's everyone's decision whether to keep it or use it for something really useful.
I believe someone thinking about the downsides of taking their salary in Bitcoin might not always be wrong, because despite the fact that Bitcoin has been growing rapidly since the beginning, we can't deny the fact that Bitcoin's price is volatile, and that volatility can be both positive and negative. In the bear market just between this bull run and the previous one, we saw Bitcoin's price going from $69k (all-time high in the previous bull run) to around $15k, so it's not that its price only goes up, but it goes down as well. And, both the ups and downs can sometimes be quick as we know.
So, imagine you agreed to receive your salary in Bitcoin, and as soon as your salary transaction is initiated, Bitcoin goes down sharply, immediately, and you lose a good amount from your salary because of that. I know, one would say that they can wait so that it recovers and then they should convert it to fiat, because obviously, if you are a salaried person, you will need funds for your daily and monthly expenses, and you won't be holding everything you get. So, if Bitcoin goes back up, it's all good, but what if it doesn't? What if it keeps going lower and lower? You won't be able to sell because that will cost you money from your salary. So, what's the solution?
That's why, there is nothing wrong in someone thinking that it's better to receive the salary in fiat, or even in a stable coin, and then if you want, you can buy Bitcoin with whatever amount you want from your salary and hold that.
