Yes it is similar if you want to buy cheaper and sell more expensive, so you want to make money on the price difference.
In principle it is almost the same, because this is an investment where bitcoin can profit if the price rises, while the stock can profit if the price goes up there is also a dividend distribution if the company gets a profit. If the loss / price falls, the risk of losing money. Because bitcoin is money, it can be used to pay for transactions, but stocks cannot be used to pay when we buy something.
