I have some questions about Crypto/Stock investment under same roof.
Binance already explained here about:
Crypto vs Stocks: What Is The Difference?, if you've read and understood about crypto and stocks, of course you won't be curious anymore why these two features can't be under one roof.
The main points and reasons can not be under one roof, you can see below.
The first difference between stocks and crypto is the market in which these two assets can be traded. Shares are traded in capital markets that operate in each country with different policies.
Whereas cryptocurrencies are transacted on the global crypto market.
That's the problem why crypto investment/trading and stocks can't be combined.
