Bitcoin market is tough and cryptocurrency market is tougher with many people while the minority of market participants see it easy and comfortable to be in and get profit with time.

Why are there different people who have different views about the same market?
It's because of their different approaches in this market.

If you see danger of altcoins, and say no with them, only spend your money for Bitcoin, especially for Bitcoin investment, you will not lose money here too easily while having so good and easy chance of getting profit.

Oppositely, if the other people are trading, especially trading altcoins, and try to identify bear trap or bull trap, you know they will be trapped by market makers after all. Eventually they stuck in traps and lose money but you can choose a first approach and avoid bad ending like them.
