Both the crypto and stock markets are volatile and subject to outside influences. However, there are also differences between them.
When we talk about cryptocurrency vs stocks, there is a big difference in the way they are traded. Cryptocurrency can be bought on a cryptocurrency exchange while you can buy stocks on the exchange. Of course, there are differences in exchanges and opening hours, as previously described.
Usually, the crypto market is more volatile than the stock market. However, the stock market is also subject to volatility due to changes in interest rates and uncertain situations such as war, inflation rate and monetary policy changes. But what about trading costs in cryptocurrency compared to stocks?
Basically, there are no transaction fees on the crypto market because it is decentralized. However, they pay a gas fee to reward the miners and validators who secure transactions on the network.
The stock market incurs transaction costs like a brokerage fee, but you can often trade for free within certain platforms like eToro that do not charge commission for stock trading.
