No, while investing in the two things can be a similar process, Bitcoins and stocks are very different.
As a cryptocurrency, Bitcoin is an asset that relies on decentralised blockchain technology with new coins generated through miners verifying transactions, and its value is determined by how much people are willing to pay for coins at any given time. Stock, on the other hand, is issued by companies in order to raise capital and their price is tied to the value of the business issuing them.
