Majority of the people lose money and this is quite disheartening in this type of market. Not everyone loses money as their are people that place short trades in the market. These people make money with it in my opinion
Those who lose money are simply those who are dumb enough to end up trading without any knowledge at all. That is certainly what most people in this space do. They opt into trading with very little knowledge and some with no knowledge at all and then think it is just about buying low and selling high. As long as you are a well learned trader, you can make money in any market.
I agreed with what you said because crypto currency trading require a lot of knowledge. Winners chapel, the short/day terms form of trading you mentioned are type of trading that require the high knowledge and I won't advice any newbie - member ranking to try it because aside of technical analysis it also require some fundamental analysis cause ones need to set a time of selling.
