If you want to be successful in the crypto world maybe you can invest in some coins that have good potential in the future, you can choose some for long-term investments, and some for short-term investments, that way you don't miss the opportunity to earn profits while you wait for the increase of your long term investment.
Before you invest in some coins, it will be better if you research to find out which coins you can buy because if you just invest in the top 10 without research, you will buy the coin at the wrong price because the price can still go down bitcoin price. But if you are okay with that, you can buy the coin from the top 10 and hold it, no matter if the price can still go down. That will be better if you do the same thing for investing in bitcoin to buy at the dip and not confuse with the price movement.
But if you follow the trading signals without research, that can give you a wrong time to enter the market because you and them will have your own target price to buy and sell. That is why you still need to analyze that trading signals before you do something so you can prevent if the market is down in the next hour.
