How it can affected hryvnia's price if the Ukraine's store didn't yet accept Bitcoin as alternative payment? President Zelenskyy not make Bitcoin as legal tender, so I doubt their citizens will use Bitcoin as a currency since most people buy Bitcoin is for investment asset. Hryvnia's price wouldn't automatically decrease when people use it to buy Bitcoin because it will make their fiat money less circulated. People will still using fiat to buy anything, the value will decrease when government print of significant amount of hryvnia.
In my opinion, the law on virtual assets adopted in Ukraine allows the use of cryptocurrency as a means of payment on the territory of Ukraine.
Thus, Article 1 of this law defines the concept of a virtual asset as follows:
virtual asset - a particular type of lane, which is valuable in electronic form, used in the system of virtual assets, which can be found in civil society.
Article 9 of this law provides for the following rights when using a virtual asset:
Participants in the virtual asset market have the right to:
1) independently collect a counterparty among participants in the virtual assets market for the purpose of conducting transactions with virtual assets;
2) take into account the post-chief services involved in the total number of virtual assets necessary, available and reliable information about such post-chief services, the rules of yoga work, the judicious transfer of minds of his operations, as well as the manifest abilities for him
3) on the basis of the quality of servants, connected with the total number of virtual assets;
4) vidkrivati and vikoristovuvati for zdiysnennya operations z virtual assets rahunka in banking and other financial institutions;
5) on the judicial and other ways to defend their rights to virtual assets, both from the side of the state, and from the side of other participants in the virtual assets market;
6) for the withdrawal of their personal data in accordance with the procedure established by the Law of Ukraine "On the withdrawal of personal data";
7) independently collect the values of virtual assets, for which operations are carried out with them.
Thus, the cryptocurrency in Ukraine has the right to fully walk in society along with other means of payment.
