I buy some coins before important events. Sometimes it makes a very good profit. But this is quite a dangerous strategy.
I think such a strategy is not too dangerous for people who are experienced, of course, and if it's a dangerous strategy, it's better not to use such a strategy because of the big risks
for people who have had experience I think risk is also a great opportunity to earn huge profits. but it is a way for those who have actually experienced, for a novice I guess it's better to learn it first.
