You have been a member on this forum for a very long time and been holding Bitcoin during that time, does that make you a good trader? Definitely not!
Crypto trading my view members here have done it, it also happened to me personally, even though I made good or bad trades, but it can make me better for myself and I feel the trading I have done and I feel the results.
I am very sure that some of the members here who carry out their trades are successful and enjoy the results of their trades, even though I don't fully know them, I am still sure there are members.
Talking about members who trade crypto, of course there are interesting things you can see in:
Topic: [Interviews] with Bitcointalk members., there is point number eight that you can see members answer about trading.
For example:
8. Do you trade on exchanges or invest in projects?
I'm better off trading on an exchange and looking for potential coins than investing in a project at the end it would be a scam too if I didn't do some research. That's a very high risk.
Hopefully this can be additional information for you about members who trade crypto here.
