I don't think there is anyone that will say that trading is completely bad because it isn't and there are people making a decent living from trading. What seems to make trading bad is the attitude of people towards trading. If you have tried trading before, you will agree with me that there is this hype and tendency to think that making money could be easy and fast from trading. This is usually the source of problem for people and the reason you see many people fail in trading. When people are so hyped and focused on the money, they tend to ignore the need to control the risk, therefore they go all in and often harm their finances so badly.
The only trading strategy which have potential to work in an unpredictable market is long term trading, which involved the trader holding for a long time period, up to few years... That is why patience is needed. On the other hand, for daily traders there aren't any assurances they are going to make guaranteed profit from this activity in a daily basis, therefore to rely a living from trading is too risky due to market's conditions.
Using the long term strategy to hodl your coins, it will give you reasonable profits than those that is using short term strategy in their hodling because it hard for the short term hodlers to earn big profits from their trading than long term traders. But there are some day traders that use to earn profits from their daily trading, but some of them are not satisfied with what they are earning from their daily trading, but the reason why they are still using the day trading is because they don't have the money to go into the long term trading because it requires money and patient in their hodling when waiting for the price of their choice to occur in the market before they can trade to earn profits..
@Zanab247, I guess that you are going off topic because this is not a trading topic and there is nothing like short-term hodler. A hodler is someone who only buy bitcoin and does not want to sell it for a very long period of time but just keep it in his possession without giving a fuck about the price of bitcoin.
Crypto price is unpredictable no matter how good you are in the crypto industry
You should be more specific on what the term
bitcoinand not crypto because shitcoins are not bitcoin and newbies might be mislead with your statement thinking shitcoin is worth investing in and hodli for long whereas only bitcoin is worth investing in and hodli for long because it is going to be more valuable in future compared to the price it is now. Bitcoin is king with great potential and should not be compared or classified with shitcoins.
