to me there is a little similarity between the two but no equal 100%. as i have also worked in stock exchange for more that 10 years so i have a good experience of stock exchange also therefore i can say that there is a little similarity between the two.
Yes, more particularly we can not use stocks as currency nor medium of exchange anywhere, but bitcoin will get you those chances. With the investment aspects, both are similar and bitcoin will get us more returns. If you are buying bitcoin only for investment purposes then it is exact you are investing into an electronic format stocks.
