If you are just holding Bitcoin you can't be called a trader because you are just buying once in a long time. A trader always do a trade, it might daily, weekly or monthly. To determine a good trader he must be profitable, because you can't be it if you were not a disciplined person, didn't have patience, and don't a trading strategy that really works because of journaling and backtesting. If you buy Bitcoin and just hold it, the better word to call you is an investor.
