why is HODLing So Popular?
I agree with the description you have for holding.
Just like the investors that gone through traditional assets, they only have to buy it and let it grow them money overtime.
No need for too much knowledge or severe understanding on it. You buy it at low price, wait until the price grows.
Provided that the coin has a good potential to grow long term like Bitcoin and Ethereum, it's the easiest way for investors to make a profit, but OP is right there are a lot of money to be made in trading if you know how, but this covesting thing is new to many of us and I'd like to read more testimonials here from people who have tried this method not testimonials coming from their homepage.
