Not at all, in my opinion a lot more need to be done before small businesses can use what they are accustomed to in every day life with crypto.
example integration with accounting software for wallets
currently most accounting software allows direct integration with bank account no such things for crypto with whats gone in and out.
How is this connected with the investors decision and the fact that they are going to sell their cryptos or not?
Do you mean that if they are to sell them, they should sell them in return of products that are going to be acquired from the companies?
I like your idea though about the integration of crypto wallets in accounting softwares.
