I always buy Altcoins when I see the up-down price of Bitcoin. When Bitcoin goes down, the maximum coin goes down. Then I can make 20%-30% profit in a few days.
But lately, I prefer to hold. If you hold, it is possible to make several times profit.
Yup, that's the thing with holding. It's the reason why we do like to do it because the profit can potentially grow effortlessly. You don't have to be great as an investor.
But, you need to be patient as much as you can so that you're going to make it when bitcoin goes up. That profit of yours with the range of 20%-30% is already good if you've been doing that every time bitcoin goes down.
