there may be time to get out of trading, when the price rose to a high bitcoin. Well, it never hurts to stop trading for a while. but, when you quit for good, I think it will only make you lose, especially when you have an expert in such matters.
Quitting for good is your decision. Theres no guarantee in trading. We all know that trading is like gambling and also risky. If you dont know what coin you are holding better prepare yourself to be rekt and get hurt.
In a casino there's the house edge. When zero falls at the roulette. Trading sites do it similar but different, you don't pay when you are unlucky but instead you pay on each and every trade, called fees. Usually just 0.2% that results in paying like 5x that a day, or -1% daily
I don't think that trading fees can be compared to house edge
You already include them in your entry and exit points. But that doesn't mean that trading is more fair than gambling. In fact, it is not, and what's more it is overall less fair than gambling, though that has nothing to do with trading fees. For example, in an honest (more or less) casino the house edge is known in advance (say, 1%), and it remains the same for all gamblers. It is not the case with Bitcoin market (or any other purely financial market, for the record). In a zero-sum game (which is what Bitcoin essentially comes down to), those who milk the market (and there are quite a few such individuals) necessarily lower the chances for the rest of the gang, and in the end their edge may be a lot more than 1%. That's basically the reason why over 90% of traders are predetermined to lose over long enough time span. In a casino you know that beforehand, in a market you don't, but this only worsens your losses due to unreasonable expectations and false hopes
