Posibility of a big dip is always there every bull run has its end and dip is always waiting for us. That is why we need to used different strategy with different coins
Yeah, there's always an end to it but I don't see it that it's coming anytime soon but just be prepared if you're too conscious with the situation and the market.
so that when time comes that we experience a huge dip we can still earn, and I guess there are a lot of altcoins that is good for short term so we need o choose those coin to gain profit.
More of the altcoins are really for the short term, you can pick a lot of it but you should have an experience doing it or if you don't have, you should be good at experimenting.
