In Bitcoin, you do not need a broker to conduct trading, and therefore the person can go directly to the cryptocurrency platform and place orders to buy and sell, so the role of broker is if there are no platforms in your country or derivatives trading (you need a license and it is high risk)
Thus, the only thing left for you is to be a crypto broker for a service that does not exist, as you can work by creating a topic here or through peer-to-peer platforms like Binance P2P, BSIQ, HODLHODL.
When it comes in comparison in between crypto and to those standard or those known traditional investment firms then it is really just on the same concept but turns out on different terms been mentioned.
If we do speak about forex/stock brokers then of course you should really be that trusting into a certain company which does really have that good standing and reputation and just like on crypto too on which
it would be that understandable that we should stick on whats the current top known or popular rather than on making yourself getting involved on which are something new.
We do know the risk of scam platforms and brokers out there and this is why we should really be that careful on dealing up with things and proceed out with caution.
