It is painful when you buy the dip and it just keeps getting dipper or you take profit and convert to usdt only to see that the coin you sold keeps pushing up in price. The best thing is to swing trade frequently and utilize stop-loss too.
The market is really unpredicted, we cant say if we made the right decision for buying or selling because we never know the next movement of the price. Thats why its better to only invest a spare money or a money you can afford to lose so whatever happens with your investment you're prepared because its not a money meant for important things.
This is what volatility means mate and also this market characteristic is why we are Earning here(of course losing as well) and also this is same reason why we love investing inside but like what you said we must put the money that we are carry to risk or gone if we cannot afford to wait longer time from the time we invested.
i have seen many people put their money and expect to grow even in 24 hours cycle,the problem is if the currency they bought suddenly fall down right after he purchase and the shit thing is will blame to the market though they have no idea about the volatile.
