Correct, trading is just like gambling. It is very risky but if you know how to manage your risk it is also profitable tough.
You just contradicted your first statement. If trading was similar to gambling then there would be no method to make it into a profitable earning method. But it can be done so. Gambling is always going to be a loss for the player because they are fighting against the odds. Trading if done on the right assets and at proper times can end up being profitable.
For now, while the crypto market suffers the sudden dump, I much prefer to HODL my bitcoin for the long term investment. It is the best time to invest and accumulate more than you can afford. Because you can't earn investing in Bitcoin in a short period of time. It needs to have patiently wait.
You can earn on a bear market too. It is called shorting but it needs practice. Check it out if you havent already. You could also bet on the prices and make money from that if you know where to find such bets.
So you are talking about some kind of gambling?? As to bet on the price and see what happens I think its good idea but people are more interested in trading nowadays I think both trading and investing are good but as per now market is bearish to better is to buy some coins at a low profit then hold them all and sell or trade later at the bullish market time yet the only thing which matter is to buy at the lowest price.
