I ve got an question

Hi everyone , i ve been longing bitcoin since the price was 17k $ and i am not familiar with the basic terms that much. I invest in couple of areas and when i hop up at that bitcoin i lowered the risks and did 7x. So my question is: in futures it says you have a bit of realized pnl . Is it my fee or something ? And i really want to hold that bitcoin position what should i do ? Should i just wait or add some more money on position i already have? Because realized pnl is also nearly %10 of money that i have on bitcoin.
