But sometimes I just use the money I get from some giveaways, raffles and others that I get for free, it makes me more comfortable to play without fear of losing that money.

That is a very nice Advantage , the simple fact of taking advantage of other income to play is already another budget , it is something to play a little more and with more ease, of course I Wish we could all have that but I am glad that you have it, however I would tell you that if you get more income try to invest in BTC which is the best, only a small part but constantly , you play and at the same time invest, it is a good Combination.
I think one of the main things for a player is observing its strenghts (which will give them an advantage as you are discussing) and their weakness
at the end of the day we should decide if we will improve in what we're already strong or if we need to improve where we are weak
there's no correct answer and each choice will bring different aspects to our game and our gambling
