Will ICO take place of IPO in near future???
No. IPO's are still one of the trusted way of investing of some usual investors and those that are not into crypto's.
They preferred this way of investing.
In other words IPO = shares while ICO = tokens.
Agree, ico has nothing to do with shares, at least most of them are so. Initial coin offering is not regulated well yet as well.
There are ICOs that offer almost the same way of earning through their tokens like IPO does.
I don't have experience and IPO's and if my understanding isn't perfect with it.
There are dividend tokens that are also sharing profit to their holders.
