If a company implements such a system for their employees and I am one of the employees of the company that will implement it, I will be happy. Of course it would be easy for me to save Bitcoin.
But, it is impossible for that to happen right now, because if that happens it means that the importance of fiat will be gradually eliminated for sure. This is what I see, of course it can be seen that Bitcoin can be used as money even digital so Fiat will lose a lot of sense in the eyes of the majority.
With HD wallets, your company can do that but as a staff and receiver of their Bitcoin payment, you must be a Bitcoin investor and understand that price can change a lot within a few hours. When you understand all these, you will not feel disappointed and panic when a few hours after receiving your salary payment in Bitcoin, its temporary value can drop to 10% or 20% lower.
You must have plan to use those bitcoin from your salary. Like when price drops 10% or 20%, you will not have to sell it to have cash.
Volatility would really be the main concern specially if you are that the employee of a certain company which do make out such changes when it comes to payment or your salary and if you are that someone who isnt prepared then you would be basically be finding out ways on making direct conversion or selling it out on the time that you would be able to received it because we do always prefer on getting our paycheck in 100% and its true that on the time that you would really be receiving it on Bitcoin form on which the value would really be making out those kind of movement on which this had been the case.It would be good if they would really be making out some meetings first or announcement on such change so that if majority of their employees wont really be liking the new system of their payment then the owner would really be giving out some options in between fiat and Bitcoin itself because it would really be just that a selfish act if you do really be deciding on forcing them out on getting one option. Always be mindful about the condition and situation that your workers
had because we know that not all would really be that agreeing on such changes.
