Depends on which side you are on. I have seen people making a living out of being fully liquid and constantly buying and selling crypto on p2p platforms. I had a friend who made that kind of money way back in the day when we didn't even had local exchanges in my nation, now we have plenty of them and he still manages to make a bit of profit because there are people who do not want to give their KYC to exchanges but his income dropped significantly and he is not making that much profit, however he already made enough crypto so he doesn't care.

Living in a nation that has no local exchange and money to your bank situation, this idea is still quite profitable. However if you are not in the crypto world and not great at it, if it is not like a business to you, then you may end up with not a great result at all, which would be basically what you would expect from a newbie.
